*    Based upon the 11,415,810 Shares outstanding as of December 11, 2002 and
     9,256,352 Shares to be issued pursuant to the option granted to the
     Purchaser under Section 1.4 of the Agreement and Plan of Merger, dated as
     of November 5, 2002, among Enghouse, Syntellect and the Purchaser.


                                   SCHEDULE TO

         This Amendment amends and supplements the Tender Offer Statement on
Schedule TO (as amended and supplemented, the "Schedule TO") initially filed on
November 13, 2002 by Enghouse Systems Limited, an Ontario corporation
("Enghouse"), and Arizona Acquisition Corp., a Delaware corporation (the
"Purchaser") and a wholly owned subsidiary of Enghouse, in connection with the
offer by the Purchaser to purchase all of the outstanding common shares, $.01
par value per share ("Shares"), of Syntellect Inc., a Delaware corporation
("Syntellect"), that are not already owned by Syntellect, the Purchaser or
Enghouse, at $0.72 per Share, net to the seller in cash, without interest, upon
the terms and subject to the conditions set forth in the Offer to Purchase dated
November 13, 2002, a copy of which is attached as Exhibit (a)(1), and in the
related Letter of Transmittal, a copy of which is attached as Exhibit (a)(2).

ITEMS 1-6, 8, 9 AND 11.

         The Offer expired at 12:00 midnight, New York City time, on Wednesday,
December 11, 2002. Based on preliminary information provided by the Depositary,
approximately 9,123,000 Shares, or approximately 80% of the outstanding Shares,
had been tendered (including 51,640 Shares tendered by notice of guaranteed
delivery). The Purchaser has accepted for payment all Shares validly tendered
prior to the expiration of the Offer and will make payment promptly to the
Depositary for the accepted Shares.

         Enghouse intends to acquire the remaining publicly held shares in a
merger in which all remaining Syntellect stockholders (other than those who
properly exercise their appraisal rights under applicable law) who did not
tender their shares in the tender offer will also receive $0.72 per share in
cash. The merger is expected to be completed promptly pursuant to the short-form
merger provisions of Delaware law.

         On Thursday, December 12, 2002, Enghouse issued a press release
announcing the final results of the Offer. A copy of the press release is
attached hereto as Exhibit (a)(8) and is incorporated herein by reference.

ITEM 12. EXHIBITS.

         Item 12 of the Schedule TO is hereby amended and supplemented to add
the following exhibit:

         (a)(8) Press Release, dated December 12, 2002.

         After due inquiry and to the best of my knowledge and belief, I certify
that the information set forth in this statement is true, complete and correct.
