The_Company

The Company	12 Months Ended
	Dec. 31, 2014
The Company [Abstract]
The Company	Note 1 - The Company
	deltathree, Inc. (the “Company”) is a global provider of integrated Voice over Internet Protocol, or VoIP, digital video and voice-over-IP services, products, hosted solutions and infrastructure. The Company was founded in 1996 to capitalize on the growth of the Internet as a communications tool by commercially offering Internet Protocol, or IP, telephony services, or VoIP telephony.  While the Company began as primarily a low-cost alternative source of wholesale minutes for carriers around the world, it has evolved into an international provider of next generation communication services.
	Going Concern
	The Company has sustained significant operating losses in recent periods, which has resulted in a significant reduction in its cash reserves.  The Company and its subsidiaries have entered into four loan agreements with D4 Holdings, LLC, its majority stockholder, pursuant to which D4 Holdings has agreed to provide the Company with loans in the aggregate principal amount of $4,100,000.  The initial Loan and Security Agreement was entered into on March 1, 2010, and the Company has drawn the maximum principal amount available under the initial Loan and Security Agreement.  On August 10, 2010, the Company and its subsidiaries entered into the Second Loan and Security Agreement, or the “Second Loan Agreement”, with D4 Holdings with a maximum principal amount of $1,000,000, and the Company has drawn the maximum principal amount available under the Second Loan Agreement.  In connection with the Second Loan Agreement, the Company issued D4 Holdings a warrant to purchase up to 4,000,000 shares of the Company's common stock at an exercise price of $0.1312 per share. On March 2, 2011, the Company and its subsidiaries entered into the Third Loan and Security Agreement, or the “Third Loan Agreement”, with D4 Holdings, pursuant to which D4 Holdings agreed to provide the Company and its subsidiaries an additional line of credit in a principal amount of $1,600,000. Pursuant to the terms of the Convertible Promissory Note, or the “Convertible Note”, issued by the Company in connection with the Third Loan Agreement, D4 Holdings may elect to convert all or any portion of the outstanding principal amount under the Convertible Note into that number of shares of the Company's common stock determined by dividing such principal amount by $0.08 (as may be adjusted under the terms of the Convertible Note). Simultaneous with the Company's entering into the Third Loan Agreement, D4 Holdings and the Company entered into an amendment of the First Loan Agreement, pursuant to which (among other things) the maturity date for repayment of principal under the First Loan Agreement was extended from March 1, 2011, to March 1, 2012, and then subsequently extended by oral agreement of the parties to July 1, 2012, and subsequently orally extended again to January 2, 2014, pending the parties finalizing and entering into a formal amendment. In connection with the Third Loan Agreement, the Company issued D4 Holdings a warrant to purchase up to 1,000,000 shares of the Company's common stock at an exercise price of $0.096 per share. The Company has drawn the aggregate principal amount available under the Third Loan Agreement, the principal amount of which can be converted by D4 Holdings into an aggregate of 20,000,000 shares of the Company's common stock. On September 12, 2011, the Company and its subsidiaries entered into the Fourth Loan and Security Agreement, or the “Fourth Loan Agreement”, with D4 Holdings, pursuant to which D4 Holdings agreed to provide the Company and its subsidiaries an additional line of credit in a principal amount of $300,000. As of December 31, 2014, the Company had received advances in the aggregate amount of $300,000 from D4 Holdings pursuant to notices of borrowing under the Fourth Loan Agreement.
	On November 13, 2012, the Company and its subsidiaries entered into the Third Amendment to Loan and Security Agreements, or the "Third Amendment", and the Amendment to Warrant Agreements, or the "Warrants Amendment", with D4 Holdings. Pursuant to the Third Amendment and the Warrants Amendment:
		•	the maturity date for repayment of principal and interest under the First Loan Agreement was extended to January 2, 2014;
		•	the maturity date for repayment of principal and interest under the Second Loan Agreement was extended to January 2, 2015;
		•	the maturity date for repayment of principal and interest under each of the Third and Fourth Loan Agreements was extended to January 2, 2016;
		•	all interest outstanding under each of the loan agreements was added to the principal amount outstanding under the respective loan agreement and the promissory notes issued pursuant to each respective loan agreement was increased by such amount; and
		•	the exercise price under each of the Warrant Agreements entered into by us and D4 Holdings as of February 12, 2009, August 10, 2010, and March 2, 2011 was amended to $0.02 per share.
	In connection with the extension of the maturity dates under the Third Amendment, the Company issued to D4 Holdings a warrant, exercisable for ten years, to purchase up to 10,000,000 shares of the Company's common stock at an exercise price of $0.02 per share.
	On January 2, 2014, the Company did not repay to D4 Holdings the outstanding principal and interest due under the First Loan Agreement, which constituted an event of default thereunder and a cross-default under all our other loan agreements with D4 Holdings. On March 28, 2014, the Company and its subsidiaries entered into a Forbearance Agreement with D4 Holdings, or the "Forbearance Agreement". Pursuant to the terms and conditions of the Forbearance Agreement, D4 Holdings agreed to forbear from taking any action with respect to the events of default until the earlier of (i) December 31, 2014, (ii) the occurrence of a breach or default by the Company or its subsidiaries under the Forbearance Agreement (which, in the event of certain undertakings of ours under the Forbearance Agreement, are not cured within three days) or (iii) the occurrence of any new or additional event of default under the Company's loan agreements with D4 Holdings. In addition, to the extent not yet perfected the Company and its subsidiaries pledged and granted as a security interest to D4 Holdings all of its right, title and interest in the collateral described in the Forbearance Agreement. In connection with the Forbearance Agreement the Company also issued to D4 Holdings a warrant, exercisable for ten years, to purchase up to 10,000,000 shares of the Company's common stock at an exercise price of $0.02 per share.
	As of December 31, 2014, the Company had negative working capital equal to approximately $8.9 million as well as negative stockholders' equity equal to approximately $8.8 million. The Company believes it is probable that it will continue to experience losses and increased negative working capital and negative stockholders' equity in the near future and will not be able to return to positive cash flow before it requires additional cash in the near term. The Company may experience difficulties accessing the equity and debt markets and raising additional capital, and there can be no assurance that the Company will be able to raise such additional capital on favorable terms or at all.  If additional funds are raised through the issuance of equity securities, the Company's existing stockholders will experience significant further dilution. Because of the Company's significant losses to date and the Company's limited tangible assets, the Company does not fit traditional credit lending criteria, which could make it difficult for the Company to obtain loans or to access the capital markets. If the Company issues additional equity or convertible debt securities to raise funds, the ownership percentage of the Company's existing stockholders would be reduced and they may experience significant dilution. New investors may demand rights, preferences or privileges senior to those of existing holders of the Company's common stock.
	The Company believes that, unless it is able to increase revenues and generate additional cash flows, its current cash and cash equivalents will not satisfy its current projected cash requirements beyond the foreseeable future. As a result, there is substantial doubt about the Company's ability to continue as a going concern.
	In addition, unless the Company is able to increase revenues and generate additional cash flows, based on currently projected cash flows the Company believes that it will be unable to pay future scheduled interest and/or principal payments under the various loan agreements with D4 Holdings as these obligations become due, and beginning January 2013 the Company suspended making scheduled interest payments with the oral consent of D4 Holdings. On January 2, 2014, the Company did not repay to D4 Holdings the outstanding principal and interest due under the First Loan Agreement, which constituted an event of default thereunder and a cross-default under all our other loan agreements with D4 Holdings, following which the Company and its subsidiaries entered into the Forbearance Agreement with D4 Holdings. In the event the Company is unable to resume making interest payments and to pay the outstanding principal when due following the termination of the Forbearance Agreement, if D4 Holdings is not willing to waive compliance or otherwise modify the Company's obligations such that the Company is able to avoid defaulting on such obligations, because D4 Holdings has a lien on all of the Company's assets to secure the Company's obligations under the loan agreements it could take actions under the loan agreements and seek to take possession of or sell the Company's assets to satisfy the Company's obligations thereunder. Any of these actions would likely have an immediate material adverse effect on the Company's business, financial condition or results of operations.
	Due to the Company's ongoing losses and reduction in cash, the Company initiated restructuring activities beginning in the second quarter of 2011 in an effort to cut operating costs significantly and better align the Company's operations with its current business model.  In accordance with the restructuring, the Company instituted a reduction in force and decreased the number of full time employees from approximately 53 to 32, reduced the salaries of all remaining employees by five percent, and decreased non-material expenses as well as payments to be made to vendors and other third parties. In addition, in December 2013 the Company instituted an additional, smaller reduction in force. As of December 31, 2014, the Company had 13 full-time employees.
	In view of the Company's current cash resources, nondiscretionary expenses, debt and near term debt service obligations, the Company may begin to explore all strategic alternatives available to it, including, but not limited to, a sale or merger of the Company, a sale of its assets, recapitalization, partnership, debt or equity financing, voluntary deregistration of its securities, financial reorganization, liquidation and/or ceasing operations. In the event that the Company requires but is unable to secure additional funding, the Company may determine that it is in its best interests to voluntarily seek relief under Chapter 11 of the U.S. Bankruptcy Code. Seeking relief under the U.S. Bankruptcy Code, even if the Company is able to emerge quickly from Chapter 11 protection, could have a material adverse effect on the relationships between the Company and its existing and potential customers, employees, and others. Further, if the Company was unable to implement a successful plan of reorganization, the Company might be forced to liquidate under Chapter 7 of the U.S. Bankruptcy Code. There can be no assurance that exploration of strategic alternatives will result in the Company pursuing any particular transaction or, if the Company pursues any such transaction, that it will be completed.

Summary of significant accounting policies	12 Months Ended
	Dec. 31, 2014
Summary of significant accounting policies [Abstract]
Summary of significant accounting policies	Note 2 - Summary of significant accounting policies
	a.      Basis of presentation
	The financial statements have been prepared in conformity with U.S. generally accepted accounting principles.
	b.      Principles of consolidation
	The consolidated financial statements include the accounts of the Company and Delta Three Israel Ltd., the Company's Israeli subsidiary (the “Subsidiary”). All significant inter-company accounts and transactions have been eliminated.
	c.        Financial statements in U.S. dollars
	The reporting currency of the Company is the U.S. dollar ("dollar"). The dollar is the functional currency of the Company and its subsidiary. Transactions and balances originally denominated in dollars are presented at their original amounts. Non-dollar transactions and balances are re-measured into dollars in accordance with the principles set forth in “Foreign Currency Matters” [ASC 830]. All exchange gains and losses from translation of monetary balance sheet items resulting from transactions in non-dollar currencies are recorded in the statement of operations as they arise.
	d.      Use of estimates
	The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the amounts reported and disclosed in the consolidated financial statement and the accompanying notes. Actual results could differ from those estimates.
	e.      Cash and cash equivalents
	Cash held in U.S. banks are subject to U.S. Federal Depository Insurance Corporation (“FDIC”) limits of $250,000 and cash held in foreign accounts are unprotected. Due to the Company's cash needs, management has generally held and continues to hold the majority of its cash in U.S. banks that are insured under the FDIC.
	f .      Restricted cash
	Restricted cash represents amounts held in cash, money market funds and certificates of deposit to support stand-by-letters of credit used as security for third party vendors, as well as amounts deposited as guarantees for the Company's office in Jerusalem and for currency hedging transactions in which the Company engages.
	g.      Inventory
	Inventory consists of the cost of customer equipment and is at the lower of cost (principally on a standard cost basis that approximates the “first-in-first-out”, or FIFO, standard) or market.
	h.      Property and equipment
	Property and equipment are stated at cost. Depreciation is calculated using the straight-line method over the estimated useful lives of the depreciable assets, which range from two to five years. Leasehold improvements are amortized based on the straight-line method over the shorter of the term of the lease, or the estimated useful life of the improvements.
	i.       Revenue recognition
	The Company recognizes revenues from VoIP telephony services based on minutes (or fractions thereof) of customer usage. The Company records payments received in advance for prepaid services and services to be supplied under contractual agreements as deferred revenue until such related services are provided.
	j.    Cost of revenues
	Cost of revenues consists primarily of direct costs that the Company pays to third parties in order to provide telephony services. These costs include access, transmission and interconnection charges that the Company pays to other access providers to terminate domestic and international phone calls on the public switched telephone network. In addition, these costs include the cost to lease phone numbers and to co-locate in other telephone companies' facilities, as well as to purchase equipment. These costs also include taxes that the Company pays on telecommunications services from its suppliers.
	The following table sets forth the different cost and expenses of our products and services per sales component for each of the years ended December 31, 2014 and 2013:
		2014							2013
	Sales Channel	Termination			Network & Access				Termination				Network & Access
	Resellers		10,256			418				11,042				478
	Direct to Consumers		82			620				209				673
	Service Providers		71			156				114				345
	Other		-			67				-				65
	Total Costs of Revenues		10,409			1,261				11,365				1,561
	k.     Research and development expenses
	Research and development expenses are expensed as incurred and consist primarily of payroll and facilities charges associated with the research and development of our current and future products.
	l.      Income taxes
	The Company provides for income taxes using the liability approach defined by “Accounting for Income Taxes” [ASC 740-10]. Deferred tax assets and liabilities are recognized for the expected tax consequences between the tax bases of the assets and liabilities and their reported amounts. Valuation allowances are established when necessary to reduce deferred tax assets to the amount expected to be realized and are reversed at such time that realization is believed to be more likely than not.
	m.     Stock-based compensation
	The following assumptions were used for the fiscal year 2014: dividend yield of 0.00% for all periods; risk-free interest rate of 1.2%; an expected life of 3-4 years for all periods; and a volatility rate of 200%.
	n.      Restricted shares and restricted units
	The Company has granted restricted shares and restricted units to purchase shares of the Company's common stock to retain, reward and motivate those employees who are deemed critical to the future success of the Company. The stock incentive plan under which the Company grants restricted share and restricted units was approved by the Board of Directors. The Company values restricted shares and restricted units to purchase shares of its common stock at the aggregate grant date fair value in accordance with ASC 718-10.
	o.      Net income (loss) per share
	Basic and diluted net income (loss) per share have been computed in accordance with “Earnings Per Share” [ASC 260-10] using the weighted average number of shares of common stock outstanding. Diluted earnings per share give effect to all potential dilutive issuances of shares of common stock that were outstanding during the period.
	p.     Concentration of credit and business risk
	The Company is subject to concentrations of credit risk, which consist principally of cash and cash equivalents, short-term investments and trade accounts receivable.
	The Company maintains its cash balances at various financial institutions. The Company performs periodic evaluations of the relative credit standing of these institutions.
	The majority of the Company's non-carrier customers prepay for their services. The Company establishes an allowance for doubtful accounts based upon factors surrounding the credit risk of customers, historical trends and other information.
	Sales to material customers representing ten percent or more of total revenues for each of the twelve months ended December 31, 2014 and 2013, and accounts receivable as of December 31, 2014, and December 31, 2013, were as follows:

	q.      Fair value of financial instruments
	The financial instruments of the Company consist mainly of cash and cash equivalents, short-term investments, current accounts receivable, accounts payable and long-term liabilities. In view of their nature, the fair value of the financial instruments included in working capital of the Company is usually identical or close to their carrying amounts.
	r.      Derivatives
	The Company applies the provisions of “Accounting for Derivative Instruments and Hedging Activities,” [ASC 815-10], as amended. The standard requires the Company to recognize all derivatives on the balance sheet at fair value. Derivatives that are not hedges must be adjusted to fair value through the statement of operations. If the derivative is a hedge, depending on the nature of the hedge, changes in the fair value of derivatives will either be offset against the change in fair value of the hedged assets, liabilities or firm commitments through earnings, or recognized in other comprehensive income (loss) until the hedged item is recognized in earnings. The ineffective portion of a derivative's change in fair value will be immediately recognized in earnings. The Company use of derivatives is immaterial.
	s.      Long-term loan from a related party
	The Second Loan Agreement and the Third Loan Agreement as described in Note 1 above are accounted for in accordance with "Debt with Conversion and Other Options" [ASC 470-20-25].
	The Second Loan Agreement was accounted as a debt instrument with stock warrants. Under ASC 470-20-25, issuers of certain debt instruments with stock purchase warrants are required to separately account for the liability components and the equity components, based on the relative fair value of the debt instrument without the warrants and of the warrants themselves at time of issuance. The Company separated it accordingly.
	The Third Loan Agreement was accounted as a convertible debt instrument with stock warrants and a beneficial conversion features. Under ASC 470-20-25, as a first step the Company separated the debt instruments and the warrants based on their relative fair value for the liability components and for the equity components. In addition, as a second step the Company concluded that the liability component includes beneficial conversion features. Under ASC 470-20-25, issuers of certain debt instruments with beneficial conversion features need to allocate to an equity component an amount based on the amount the feature is in-the-money at the commitment date. The Company separated it accordingly.
	On November 13, 2012, we and our subsidiaries entered into the Third Amendment to Loan and Security Agreements, or the "Third Amendment", and the Amendment to Warrant Agreements, or the "Warrants Amendment", with D4 Holdings. Pursuant to the Third Amendment and the Warrants Amendment, we have regarded the restructured long-term debt to D4 Holdings, under the criteria of, and have accounted for the restructured long-term debt as, a troubled debt restructuring in accordance with ASC Subtopic 470-60, “Debt - Troubled Debt Restructurings by Debtors”, which requires that the gross future cash flows of principal and interest be reflected in the balance sheet.
	The interest expenses relating to both the contractual interest coupon and amortization of the discount on the liability component are as follows:
			December 31,
			2014			2013
		($ in thousands)
Contractual interest coupon			683			590
Amortization of the discount on the liability components			464			169

Severance pay obligations	Note 8 - Severance pay obligations
	The Subsidiary is subject to certain Israeli laws and labor agreements that determine the obligations of the Subsidiary to make severance payments to employees who have been terminated and who are leaving the employment of the Subsidiary under certain other circumstances. The amount of severance pay benefits requirement to be paid is determined based upon the employee's length of service and the employee's salary at the time of termination. This obligation is partially funded through regular deposits made by the Subsidiary into accounts maintained by unaffiliated third party insurance company funds for managers' insurance policies. Amounts deposited are controlled by the fund trustees and insurance companies and are not under the control and management of the Subsidiary.
	Expenses relating to employee termination benefits were $92,132, $113,745 and $107,689 for the years ended December 31, 2014, 2013 and 2012, respectively.
	The aggregate value of the insurance policies as of December 31, 2014 and 2013 was $580,133 and $901,362, respectively.

	We lease our executive offices at 1 Bridge Plaza, Suite #275, Fort Lee, New Jersey, and storage and equipment space at 117 Central Avenue, Hackensack, New Jersey. We lease each of these facilities on a month-to-month basis. The aggregate rent expense, net, for the two locations for 2014 was $7,000.
	The Subsidiary, leases an office that houses our research and development facilities in Jerusalem, Israel. The term of the lease is until June 30, 2015. Rent expense, net, for our subsidiary, for 2014 was $125,000.
		b.	Legal proceedings
	On July 5, 2011, the Company received a notice from the New York City Department of Finance that claimed that the Company had not paid commercial rent tax required under the New York City Administrative Code from June 1998 through May 2008 for the two offices that the Company had leased during that time. The notice stated that the Company is obligated to pay the outstanding tax amounts, as well as significant interest and penalties that were assessed on the unpaid amounts as well as for the failure to file the applicable tax returns. The Company engaged outside counsel, which began discussions with the Department of Finance, and contested assessment and simultaneously attempted to negotiate a significant reduction in the amounts to be paid. The Company's appeal was rejected in July 2012 by an examiner in the Department of Finance, and the Company has subsequently engaged and begun discussions with a manager in the Department of Finance and submitted additional supporting materials. The final outcome of this assessment and the Company's negotiations with the New York City Department of Finance cannot be determined at this time. In the event that the Company is required to pay all or most of the amounts claimed by the New York City Department of Finance this would have a material adverse effect on the Company's financial condition and liquidity. During 2011 the Company recorded $300,000 as a provision for commercial rent tax. The Company has determined that $300,000 is the minimum amount that would settle the claim according to ASC 450-20. The amount claimed by the Department of Finance was approximately $912,000; as a result, there is a reasonable possibility that a loss in excess of the $300,000 would be incurred.
	In addition, from time to time the Company is a party to legal proceedings, much of which is ordinary routine litigation incidental to the business, and is regularly required to expend time and resources in connection with such proceedings. Accordingly, the Company, in consultation with its legal advisors, accrues amounts that management believes it is probable the Company will be required to expend in connection with all legal proceedings to which it is a party.
	c. Regulation
	Although there are several regulatory proceedings currently pending before federal authorities, providers of interconnected VoIP services are lightly regulated compared to providers of traditional telecommunications services. On February 12, 2004, the FCC initiated a generic rulemaking proceeding concerning the provision of voice and other services using IP technology, including assessing whether VoIP services should be classified as information services or telecommunications services. The rulemaking is ongoing and we cannot predict the outcome of this proceeding. In November 2004, the FCC determined that certain interconnected VoIP services (meaning VoIP services that can be used to send and receive calls to or from the PSTN), including some services that are similar to ours, should be considered interstate services subject to federal rather than state jurisdiction.  Although this ruling was appealed by several states, on March 21, 2007, the United States Court of Appeals for the Eighth Circuit affirmed the FCC's determination.
	The FCC's generic rulemaking proceeding could result in the FCC determining, for instance, that certain types of Internet telephony should be regulated like basic telecommunications services. Thus, Internet telephony would no longer be exempt from more onerous telecommunications-related regulatory obligations, could potentially become subject to state telecommunications regulations, and could become subject to other economic regulations typically imposed on traditional telecommunications carriers.
	On June 3, 2005, the FCC released an order and notice of proposed rulemaking concerning VoIP emergency 911 services. The order set forth two primary requirements for providers of interconnected VoIP services. The order applies to our iConnectHere and joip customers, or our “direct customers”. We do not believe that we are responsible for compliance with this order when we sell our service wholesale to companies who then offer the service to retail end-users. We cannot predict whether we would be subject to any third-party litigation in connection with such customers who resell our services or whether the rules will be interpreted as applicable to those who wholesale interconnected VoIP services.
	The order set forth two primary requirements for providers of interconnected VoIP services. First, the order requires providers of interconnected VoIP services like us to notify our retail customers of the differences between the emergency services available through our offerings and those available through traditional telephony providers. We also had to receive affirmative acknowledgment from some of our retail customers that they understand the nature of the emergency services available through our service. On September 27, 2005, the FCC's Enforcement Bureau released an order stating that the Enforcement Bureau will not pursue enforcement actions against interconnected VoIP providers that have received affirmative acknowledgement from at least 90% of their subscribers. We received affirmative acknowledgment from more than 95% of our relevant customers that they understand the nature of the emergency services available through our service, and thus we believe we are substantially in compliance with the first aspect of the FCC's June 3 order.
	Second, the order required providers of interconnected VoIP services like us to offer enhanced emergency dialing capabilities, or E-911, to all of our retail customers by November 28, 2005. Under the terms of the order, we are required to use the dedicated wireline E-911 network to transmit customers' 911 calls, callback number and customer-provided location information to the emergency authority serving the customer's specified location. On November 7, 2005, the FCC's Enforcement Bureau issued a Public Notice with respect to that requirement. The Public Notice indicated that providers who have not fully complied with the enhanced emergency dialing capabilities requirement are not required to discontinue the provision of services to existing customers, but that the FCC expects that such providers will discontinue marketing their services and accepting new customers in areas in which the providers cannot offer enhanced emergency dialing capabilities where such capabilities are otherwise available.
	Almost all of our retail customers currently receive E-911 service in conformity with the FCC's order. Like many interconnected VoIP providers, we rely on third parties to route emergency calls originated by our customers. In certain instances and for some of our customers, the third party provider may route 911 calls to an unofficial emergency call center. Such unofficial call centers may not be able to receive appropriate call back information. To the extent that they are so able or callers provide their location information the emergency dispatchers in such call centers may not then be able to route such calls to the appropriate public safety answering point. The FCC could find that routing calls routed in this manner violates its rules, potentially subjecting us to enforcement actions including, but not limited to, fines, cease and desist orders, or other penalties. Moreover, some customers who were receiving service prior to the FCC's deadline for compliance with the E-911 regulations may not receive such service. The FCC permitted service providers to continue to provide service to those existing customers rather than disconnect those customers. Pursuant to the FCC's requirement, after the implementation of the FCC E-911 requirements, we provide services to our new retail customers only where we can provide the FCC required E-911 service. We may be required to stop serving those customers to whom we cannot provide the required enhanced emergency dialing capabilities that were being serviced prior to the issuance of the FCC's rules at any time.
	The FCC is considering modifying its VoIP E-911 rules.  In June, 2007, the FCC released a Notice of Proposed Rulemaking to consider whether it should impose additional obligations on interconnected VoIP providers.  Specifically, the FCC considered mandating that interconnected VoIP providers implement a solution that will allow for automatically determining the location of their customers for purposes of E-911 rather than require customers to manually update their existing location information (as is the case under the current regulations).  Moreover, the Notice included a tentative conclusion that interconnected VoIP providers that allow their service to be used in more than one location, like us, be required to meet the same customer location accuracy standards applicable to providers of mobile telecommunications services.  In September 2010, the FCC released a Notice of Inquiry again requesting comment on, among other issues, whether interconnected VoIP providers should be required to provide automatic location information about their customers rather than requiring customers to self-report their location.  Additionally, the Notice of Inquiry sought comment on whether the FCC's rules concerning the delivery of emergency services should be extended to non-interconnected VoIP services as well as to mobile VoIP applications used on smartphones, computers and other devices.  At this time we cannot predict the outcome of these proceedings or their potential impact on our business.
	The Communications Assistance for Law Enforcement Act, or CALEA, requires certain communications service providers to assist law enforcement agencies in conducting lawfully authorized electronic surveillance. On September 23, 2005, the FCC released an order concluding that CALEA applies to interconnected VoIP providers.  In May 2006 the FCC released an order finding that broadband Internet access service providers and interconnected VoIP providers are required to implement the same type of CALEA requirements that have been applied to wireline telecommunications carriers. These include obligations to (1) ensure that communications equipment, facilities, and services meet interception assistance capability requirements and (2) develop system security policies and procedures to define employee supervision and record retention requirements.  As a result of the steps the Company has taken, we believe that we comply with CALEA.
	The FCC decided in June 2006 that interconnected VoIP service providers should be required to contribute to the universal service fund, or USF. The amount of universal service contribution for interconnected VoIP service providers is based on a percentage of revenues earned from end-user interstate services. The FCC developed three alternatives under which an interconnected VoIP service provider may elect to calculate its universal service contribution: (1) a safe harbor that assumes 64.9% of the provider's end-user revenues are interstate; (2) a traffic study to determine an allocation for interstate end-user revenues; or (3) actual interstate and international end-user revenues. If an interconnected VoIP service provider calculates its universal service contributions based on its actual percentage of interstate calls, the FCC suggested that its preemption of state regulation of such services may no longer apply, in which case the interconnected VoIP service provider could be subject to regulation by each state in which it operates as well as federal regulation. In addition, the FCC is considering a number of proposals that could alter the way that the USF is assessed. For instance, the FCC is considering an assessment based on the use of telephone numbers. The U.S. Congress may also provide the FCC with additional authority to reform USF or mandate a particular methodology.  At this time we cannot predict time what impact, if any, USF reform, may have on our business.
	Numerous states may attempt to impose state universal service contribution requirements on interconnected VoIP providers such as deltathree. At this time, various states – including Kansas, Nebraska and New Mexico – claim that they have the right to require interconnected VoIP providers to contribute to their respective USF funds.  On March 3, 2008, the U.S. District Court for Nebraska issued a preliminary injunction and found that Nebraska's state Public Service Commission does not have jurisdiction to require Universal Service contributions from VoIP providers. On May 1, 2009, a panel of the U.S. Circuit Court of Appeals for the Eighth Circuit affirmed the U.S. District court ruling. In response, the Nebraska and New Mexico state commissions filed a petition with the FCC seeking the authority to impose state USF contribution obligations on interconnected VoIP providers, like us, and the FCC granted the petition.  As a result of this ruling, a number of other states have either stated that offerings such as ours may be subject to their respective state USF or are considering imposing such obligations on us.  We would likely pass through to our customers in those states any such state USF fees, potentially making our services less competitive with offerings available from traditional providers of telecommunications services, which may cause us to lose customers in those states.   In addition, in the past some states have attempted to impose retroactive application of any state USF obligations. Retroactive applicability of any state USF fees would effectively bar us from collecting such fees from our customers, s reducing our future profits.
	On April 2, 2007, the FCC issued an order that tightened existing rules on protection and use of Customer Proprietary Network Information, or CPNI, and extended coverage of the CPNI rules to interconnected VoIP service providers. Among other things, the Order imposes greater obligations on us and other companies like us to protect CPNI, acquire customer consent prior to engaging in certain kinds of marketing efforts based on CPNI, train our employees concerning protecting (and the use of) CPNI and to file formal certifications with the FCC regarding procedures for protecting this information.  As a result of the steps we have taken, we believe that we comply with this Order.
	On June 15, 2007, and effective October 5, 2007, interconnected VoIP providers, like us, became required to, among other things, make certain that their equipment and service is accessible to and usable by individuals with disabilities, if readily achievable. In addition, interconnected VoIP providers like us became obligated to contribute to the Telecommunications Relay Services, or TRS, fund and to offer 711 abbreviated dialing for access to relay services. Following March 31, 2009, interconnected VoIP providers are required to route such 711 calls to the appropriate TRS relay center serving the state in which the caller is located or the relay center corresponding to the caller's last registered address.  As a result of the steps we have taken, we believe that we comply with the applicable requirements.
	On August 6, 2007 and effective November 2007, the FCC adopted an Order concerning the collection of regulatory fees for Fiscal Year 2007 requiring the collection of such fees from interconnected VoIP providers like us. Like other interconnected VoIP providers, we now pay regulatory fees based on interstate and international revenues.
	On November 8, 2007, the FCC released an Order relating to local number portability imposing local number portability, or LNP, and related obligations on interconnected VoIP Providers like us. The Order requires interconnected VoIP providers to contribute to shared numbering administration costs. Additionally, the Order mandates that we process certain kinds of telephone number porting requests within certain timeframes.  As a result of the steps we have taken, we believe that we comply with this Order. Subsequently, on May 13, 2009, the FCC released another order concerning LNP that further reduces the porting timeframe for certain types of telephone number porting requests that interconnected VoIP providers, like us, have to process. Since we are not a licensed telecommunications carrier, we must rely on third parties to comply with these porting obligations. If these third parties fail to comply with these obligations we could be subject to fines, forfeitures and other penalties by the FCC or state public utilities commissions or we could face legal liability in state or federal court from customers or carriers. The FCC also released a Further Notice of Proposed Rulemaking to refresh the record on how to further improve the porting process, and how to potentially expand the new one business day porting timeframe to other kinds of ports. We cannot predict the outcome of this proceeding or its potential impact on us at this time.
	The FCC is actively considering reform of the intercarrier compensation system, which is a set of FCC rules and regulations by which telecommunications carriers compensate each other for the use of their respective networks. These rules and regulations affect the prices we pay to our suppliers for access to the facilities and services that they provide to us, such as termination of calls by our customers onto the public switched telephone network. At this time we cannot predict what impact, if any, new intercarrier compensation regulations would have on our business.
	In May 2009, the FCC extended to interconnected VoIP providers like us the discontinuance rules that previously applied only to non-dominant common carriers. The FCC's rules require non-dominant domestic carriers to provide notice to customers at least 30 days prior to discontinuing service to a telephone exchange, toll stations serving a community in whole or in part, and other similar activities that affect a community or part of a community. Carriers must inform certain state authorities of the discontinuation, and obtain prior FCC approval before undertaking the service disruption. The FCC's rules allow for streamlined treatment for FCC discontinuance approvals and interconnected VoIP providers will be able to take advantage of the same streamlined procedures afforded to non-dominant carriers. It is not yet clear how these rules apply to interconnected VoIP providers. But in the event we discontinue one of our service offerings in its entirety or if we were to exit the market in whole we would likely have to comply with these new rules. We do not expect these new obligations to have a material impact on our business.
	In June 2007, the FCC adopted various recommendations from its Independent Panel Reviewing the Impact of Hurricane Katrina on Communications Networks Panel, including a requirement that certain interconnected VoIP providers submit reports regarding the reliability and resiliency of their 9-1-1 systems. At this time, we are not subject to these reporting requirements but may become subject in the future.
	We rely upon providers of broadband Internet access services to offer our services to our customers. The FCC recently adopted “open Internet” rules that would, among other things, prohibit fixed providers of broadband Internet access services from blocking, impairing or downgrading such access.  Wireless providers of broadband Internet access services would be prohibited from blocking VoIP applications like ours.  The open Internet rules are not yet effective and, as a result of both legislative efforts to overturn the rules as well as potential appeals of the passage of the rules, it is unclear whether (and when) the rules will become effective.  While we are not aware of any provider of broadband Internet access attempting to interfere with our Internet access, the lack of enforceable rules could potentially negatively impact our service offerings and impede our ability to offer new services that require significant Internet bandwidth.
	In addition, some state and local regulatory authorities believe they retain jurisdiction to regulate the provision of, and impose taxes, fees and surcharges on, intrastate Internet and VoIP telephony services, and have attempted to impose such taxes, fees and surcharges, such as a fee for providing E-911 service. Rulings by the state commissions on the regulatory considerations affecting Internet and IP telephony services could affect our operations and revenues, and we cannot predict whether state commissions will be permitted to regulate the services we offer in the future.
	The Company paid approximately $11,000of state and local taxes and other fees during 2014.  To the extent we increase the cost of services to its customers to recoup some of the costs of compliance; this will have the effect of decreasing any price advantage we may have over traditional telecommunications companies.
	In addition, it is possible that we will be required to collect and remit taxes, fees and surcharges in other states and local jurisdictions where we have not done so, and which such authorities may take the position that we should have collected. If so, they may seek to collect those past taxes, fees and surcharges from us and impose fines, penalties or interest charges on us. Our payment of these past taxes, fees and surcharges, as well as penalties and interest charges, could have a material adverse effect on us.

		b.	Change in Control
	On February 10, 2009, the Company entered into the Purchase Agreement with D4 Holdings pursuant to which the Company issued to D4 Holdings the Shares, representing approximately 54.3% of the total number of issued and outstanding shares of Common Stock following the transaction, for an aggregate purchase price of $1,170,000, payable in cash, and the Warrant, exercisable for ten years, to purchase up to an additional 30,000,000 shares of Common Stock at an exercise price of $0.04 per share.  The transaction closed on February 12, 2009.
	In connection with the closing of the transaction and pursuant to the terms of the Purchase Agreement, Noam Bardin resigned as a director and the board of directors appointed Robert Stevanovski and Anthony Cassara to serve on the board.  In addition, Lior Samuelson resigned as Chairman of the Board and remained a director, and Robert Stevanovski was appointed to serve as Chairman.  Under the terms of the Purchase Agreement, D4 Holdings had the right to nominate for appointment by the board one director in addition to Messrs. Stevanovski and Cassara, and it nominated David Stevanovski.  In addition, on March 4, 2009, the Board of Directors of the Company increased the size of the board from five to seven members and filled the two vacancies remaining on the board by appointing Gregory Provenzano and J. Lyle Patrick as directors.   The appointments of the three new directors to serve on the board became effective on March 28, 2009.
	As a result of the transaction between the Company and D4 Holdings, D4 Holdings obtained a controlling interest in the Company.

		a.	Provision for income taxes
	No provision for income taxes was required for the years ended December 31, 2014, 2013 and 2012 due to net losses in these periods.
		b.	Net operating losses
	As of December 31, 2014, the Company had net operating losses generated in the U.S. and Israel of approximately $23.6 million and $3.9 million, respectively.
	The Company's issuance of common stock to D4 Holdings in February 2009 constituted an “ownership change” as defined in Section 382 of the Internal Revenue Code. As a result, under Section 382 the Company's ability to utilize NOLs generated in the U.S. prior to February 2009 (equal to approximately $156 million) to offset any income it may generate in the future will be limited to approximately $600,000 per year from February 2009.  The NOLs began expiring in 2011 and will expire at various dates until 2029 if not utilized. The Company's ability to utilize its remaining NOLs could be additionally reduced if it experiences any further “ownership change,” as defined under Section 382.
	The Company's net operating losses generated in Israel may be carried forward indefinitely. The Subsidiary received final tax assessments through the tax year ended December 31, 2008.
		c.	In accordance with ASC 740-10, the components of deferred income taxes are as follows:

Subsequent Events	Note 16 – Subsequent Events
	On February 25, 2015, D4 Holdings sent a letter to our board of directors that indicated that within three to four weeks of the date of the letter D4 Holdings intended to initiate a tender offer to purchase all of the outstanding shares of our common stock not owned by D4 Holdings at a purchase price of $0.01 per share in cash. D4 Holdings stated that it is not willing to enter into further forbearance arrangements with us or to provide us additional financing. Finally, D4 Holdings indicated that, in its capacity as majority stockholder of our company, it is presently not interested in either selling its shares or voting in favor of any alternative transaction, including a merger of sale of our assets or business or similar transaction.
	On March 26, 2015 D4 Holdings sent a letter to our board of directors that indicated that D4 Holdings withdraws its previous offer and instead proposes to acquire us through a merger of our company with a newly-formed acquisition subsidiary of D4 Holdings. The transaction will be structured as a stock purchase, pursuant to which D4 Holdings will purchase all of the outstanding shares of our common stock not owned by D4 Holdings. D4 Holdings restated its previous offer of $0.01 per share, to be paid in cash from its own funds, and accordingly there will be no financing contingency. In addition, D4 Holdings will assume all of our outstanding debt, currently valued at approximately $7.9 million.
	The completion of the transaction will be conditioned upon, among other things, approval by a special committee of our board of directors consisting of independent directors. If the transaction is completed, our common stock will no longer be registered under Section 12 of the Exchange Act.

Summary of significant accounting policies (Policies)

Dec. 31, 2014

Summary of significant accounting policies [Abstract]

Basis of presentation

a.      Basis of presentation

The financial statements have been prepared in conformity with U.S. generally accepted accounting principles.

Principles of consolidation

b.      Principles of consolidation

The consolidated financial statements include the accounts of the Company and Delta Three Israel Ltd., the Company's Israeli subsidiary (the “Subsidiary”). All significant inter-company accounts and transactions have been eliminated.

Financial statements in U.S. dollars

c.        Financial statements in U.S. dollars

The reporting currency of the Company is the U.S. dollar ("dollar"). The dollar is the functional currency of the Company and its subsidiary. Transactions and balances originally denominated in dollars are presented at their original amounts. Non-dollar transactions and balances are re-measured into dollars in accordance with the principles set forth in “Foreign Currency Matters” [ASC 830]. All exchange gains and losses from translation of monetary balance sheet items resulting from transactions in non-dollar currencies are recorded in the statement of operations as they arise.

Use of estimates

d.      Use of estimates

The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the amounts reported and disclosed in the consolidated financial statement and the accompanying notes. Actual results could differ from those estimates.

Cash and cash equivalents

e.      Cash and cash equivalents

Cash held in U.S. banks are subject to U.S. Federal Depository Insurance Corporation (“FDIC”) limits of $250,000 and cash held in foreign accounts are unprotected. Due to the Company's cash needs, management has generally held and continues to hold the majority of its cash in U.S. banks that are insured under the FDIC.

Restricted cash

f .      Restricted cash

Restricted cash represents amounts held in cash, money market funds and certificates of deposit to support stand-by-letters of credit used as security for third party vendors, as well as amounts deposited as guarantees for the Company's office in Jerusalem and for currency hedging transactions in which the Company engages.

Inventory

g.      Inventory

Inventory consists of the cost of customer equipment and is at the lower of cost (principally on a standard cost basis that approximates the “first-in-first-out”, or FIFO, standard) or market.

Property and equipment

h.      Property and equipment

Property and equipment are stated at cost. Depreciation is calculated using the straight-line method over the estimated useful lives of the depreciable assets, which range from two to five years. Leasehold improvements are amortized based on the straight-line method over the shorter of the term of the lease, or the estimated useful life of the improvements.

Revenue recognition

i.       Revenue recognition

The Company recognizes revenues from VoIP telephony services based on minutes (or fractions thereof) of customer usage. The Company records payments received in advance for prepaid services and services to be supplied under contractual agreements as deferred revenue until such related services are provided.

Cost of revenues

j.    Cost of revenues

Cost of revenues consists primarily of direct costs that the Company pays to third parties in order to provide telephony services. These costs include access, transmission and interconnection charges that the Company pays to other access providers to terminate domestic and international phone calls on the public switched telephone network. In addition, these costs include the cost to lease phone numbers and to co-locate in other telephone companies' facilities, as well as to purchase equipment. These costs also include taxes that the Company pays on telecommunications services from its suppliers.

The following table sets forth the different cost and expenses of our products and services per sales component for each of the years ended December 31, 2014 and 2013:

Research and development expenses

k.     Research and development expenses

Research and development expenses are expensed as incurred and consist primarily of payroll and facilities charges associated with the research and development of our current and future products.

Income taxes

l.      Income taxes

The Company provides for income taxes using the liability approach defined by “Accounting for Income Taxes” [ASC 740-10]. Deferred tax assets and liabilities are recognized for the expected tax consequences between the tax bases of the assets and liabilities and their reported amounts. Valuation allowances are established when necessary to reduce deferred tax assets to the amount expected to be realized and are reversed at such time that realization is believed to be more likely than not.

Stock-based compensation

m.     Stock-based compensation

The following assumptions were used for the fiscal year 2014: dividend yield of 0.00% for all periods; risk-free interest rate of 1.2%; an expected life of 3-4 years for all periods; and a volatility rate of 200%.

Restricted shares and restricted units

n.      Restricted shares and restricted units

The Company has granted restricted shares and restricted units to purchase shares of the Company's common stock to retain, reward and motivate those employees who are deemed critical to the future success of the Company. The stock incentive plan under which the Company grants restricted share and restricted units was approved by the Board of Directors. The Company values restricted shares and restricted units to purchase shares of its common stock at the aggregate grant date fair value in accordance with ASC 718-10.

Net income (loss) per share

o.      Net income (loss) per share

Basic and diluted net income (loss) per share have been computed in accordance with “Earnings Per Share” [ASC 260-10] using the weighted average number of shares of common stock outstanding. Diluted earnings per share give effect to all potential dilutive issuances of shares of common stock that were outstanding during the period.

Concentration of credit and business risk

p.     Concentration of credit and business risk

The Company is subject to concentrations of credit risk, which consist principally of cash and cash equivalents, short-term investments and trade accounts receivable.

The Company maintains its cash balances at various financial institutions. The Company performs periodic evaluations of the relative credit standing of these institutions.

The majority of the Company's non-carrier customers prepay for their services. The Company establishes an allowance for doubtful accounts based upon factors surrounding the credit risk of customers, historical trends and other information.

Sales to material customers representing ten percent or more of total revenues for each of the twelve months ended December 31, 2014 and 2013, and accounts receivable as of December 31, 2014, and December 31, 2013, were as follows:

Fair value of financial instruments

q.      Fair value of financial instruments

The financial instruments of the Company consist mainly of cash and cash equivalents, short-term investments, current accounts receivable, accounts payable and long-term liabilities. In view of their nature, the fair value of the financial instruments included in working capital of the Company is usually identical or close to their carrying amounts.

Derivatives

r.      Derivatives

The Company applies the provisions of “Accounting for Derivative Instruments and Hedging Activities,” [ASC 815-10], as amended. The standard requires the Company to recognize all derivatives on the balance sheet at fair value. Derivatives that are not hedges must be adjusted to fair value through the statement of operations. If the derivative is a hedge, depending on the nature of the hedge, changes in the fair value of derivatives will either be offset against the change in fair value of the hedged assets, liabilities or firm commitments through earnings, or recognized in other comprehensive income (loss) until the hedged item is recognized in earnings. The ineffective portion of a derivative's change in fair value will be immediately recognized in earnings. The Company use of derivatives is immaterial.

Long-term loan from a related party

s.      Long-term loan from a related party

The Second Loan Agreement and the Third Loan Agreement as described in Note 1 above are accounted for in accordance with "Debt with Conversion and Other Options" [ASC 470-20-25].

The Second Loan Agreement was accounted as a debt instrument with stock warrants. Under ASC 470-20-25, issuers of certain debt instruments with stock purchase warrants are required to separately account for the liability components and the equity components, based on the relative fair value of the debt instrument without the warrants and of the warrants themselves at time of issuance. The Company separated it accordingly.

The Third Loan Agreement was accounted as a convertible debt instrument with stock warrants and a beneficial conversion features. Under ASC 470-20-25, as a first step the Company separated the debt instruments and the warrants based on their relative fair value for the liability components and for the equity components. In addition, as a second step the Company concluded that the liability component includes beneficial conversion features. Under ASC 470-20-25, issuers of certain debt instruments with beneficial conversion features need to allocate to an equity component an amount based on the amount the feature is in-the-money at the commitment date. The Company separated it accordingly.

On November 13, 2012, we and our subsidiaries entered into the Third Amendment to Loan and Security Agreements, or the "Third Amendment", and the Amendment to Warrant Agreements, or the "Warrants Amendment", with D4 Holdings. Pursuant to the Third Amendment and the Warrants Amendment, we have regarded the restructured long-term debt to D4 Holdings, under the criteria of, and have accounted for the restructured long-term debt as, a troubled debt restructuring in accordance with ASC Subtopic 470-60, “Debt - Troubled Debt Restructurings by Debtors”, which requires that the gross future cash flows of principal and interest be reflected in the balance sheet.

The interest expenses relating to both the contractual interest coupon and amortization of the discount on the liability component are as follows:
