Ladies and Gentleman:

     We refer to the Registration Statement on Form S-8 (the "Registration
Statement") to be filed with the Securities and Exchange Commission under the
Securities Act of 1933, as amended (the "Act"), on behalf of TTI Team Telecom
International Ltd. (the "Company"), relating to 1,000,000 of the Company's
Ordinary Shares, NIS 0.50 nominal value per share (the "Shares"), to be issued
upon the exercise of share options granted under the TTI Team Telecom
International Ltd. 2004 Employee Share Option Plan (the "Plan").

     We are members of the Israeli Bar and we express no opinion as to any
matter relating to the laws of any jurisdiction other than the laws of Israel.

     As counsel for the Company, we have examined such corporate records, other
documents, and such questions of Israeli law as we have considered necessary or
appropriate for the purposes of this opinion and, upon the basis of such
examination, advise you that in our opinion, the Shares have been duly
authorized and, when issued and paid for in accordance with the terms of the
Plan, will be validly issued, fully paid and non-assessable.

     We hereby consent to the filing of this opinion as an exhibit to the
Registration Statement. This consent is not to be construed as an admission that
we are a person whose consent is required to be filed with the Registration
Statement under the provisions of the Act.

                                                  Very truly yours,

                                                  /S/ Goldfarb, Levy, Eran & CO.
