To Brokers, Dealers, Commercial Banks, Trust Companies and Other Nominees:

     We have been appointed by Arizona Acquisition Corp., a Delaware corporation
(the "Purchaser") and a wholly owned subsidiary of Enghouse Systems Limited, an
Ontario corporation ("Enghouse"), to act as Information Agent in connection with
the Purchaser's offer to purchase all outstanding shares of common stock, par
value $.01 per share (the "Shares"), of Syntellect Inc., a Delaware corporation
("Syntellect"), at a price of US$0.72 per Share, net to the seller in cash,
without interest thereon (the "Offer Price"). The Offer to Purchase dated
November 13, 2002 (the "Offer to Purchase") and the related Letter of
Transmittal enclosed herewith, together with any amendments or supplements to
either of them, collectively constitute the "Offer" as used in this letter.

     Holders of Shares whose certificates for such Shares (the "Share
Certificates") are not immediately available, who cannot complete the procedures
for book-entry transfer on a timely basis, or who cannot deliver all other
required documents to Computershare Trust Company of New York (the "Depositary")
prior to the Expiration Date (as defined in the Offer to Purchase) must tender
their Shares according to the guaranteed delivery procedures set forth in
Section 3 (Procedures for Accepting the Offer and Tendering Shares) of the Offer
to Purchase.

     The Offer is conditioned upon, among other things, there being validly
tendered in accordance with the terms of the Offer and not properly withdrawn
prior to the Expiration Date a number of Shares that, together with any
outstanding Shares solely owned by Enghouse or any of its subsidiaries,
constitutes a majority of the outstanding Shares (determined on a fully diluted
basis). The Offer is also subject to other conditions described in Section 15
(Certain Conditions of the Offer) of the Offer to Purchase.

     Please furnish copies of the enclosed materials to those of your clients
for whose accounts you hold Shares registered in your name or in the name of
your nominee:

          1.  Offer to Purchase dated November 13, 2002;

          2.  Letter of Transmittal for your use in accepting the Offer and
     tendering Shares and for the information of your clients (manually signed
     facsimile copies of the Letter of Transmittal may be used to tender
     Shares);

          3.  Notice of Guaranteed Delivery to be used to accept the Offer if
     Share Certificates are not immediately available or if such Share
     Certificates and all other required documents cannot be delivered to the
     Depositary prior to the Expiration Date, or if the procedures for
     book-entry transfer cannot be completed on a timely basis;


          4.  A printed form of letter which may be sent to your clients for
     whose accounts you hold Shares registered in your name or in the name of
     your nominee, with space provided for obtaining such clients' instructions
     with regard to the Offer;

          5.  The letter to stockholders of Syntellect from Anthony V. Carollo,
     Jr., the Chief Executive Officer of Syntellect, accompanied by Syntellect's
     Solicitation/Recommendation Statement on Schedule 14D-9 filed with the
     Securities and Exchange Commission by Syntellect, which includes the
     recommendation of the Board of Directors of Syntellect that stockholders
     accept the Offer and tender their Shares to Purchaser pursuant to the
     Offer;

          6.  Guidelines for Request for Taxpayer Identification Number and
     Certification on Substitute Form W-9; and

          7.  A return envelope addressed to the Depositary.

     The Offer is being made pursuant to an Agreement and Plan of Merger (the
"Merger Agreement"), dated as of November 5, 2002, among Enghouse, the Purchaser
and Syntellect, pursuant to which, following the purchase by Purchaser of Shares
in the Offer and the satisfaction or waiver of each of the conditions to the
Offer set forth in the Merger Agreement, the Purchaser will be merged with and
into Syntellect (the "Merger"), with Syntellect surviving the Merger as a wholly
owned subsidiary of Enghouse. As a result of the Merger, each outstanding Share
of Syntellect (other than Shares owned by Enghouse, the Purchaser, Syntellect or
any of their respective subsidiaries, or by stockholders, if any, who properly
exercise appraisal rights under Delaware law) will be converted into the right
to receive the Offer Price in cash.

     The Board of Directors of Syntellect has, at a meeting held on November 5,
2002, unanimously (i) approved the Merger Agreement, (ii) approved the Offer and
the Merger and certain other actions described in the Merger Agreement, (iii)
determined that the Merger Agreement and the transactions contemplated thereby,
including the Offer and the Merger, are fair to, and in the best interests of,
Syntellect and its stockholders and (iv) recommended that Syntellect's
stockholders accept the Offer, tender their Shares pursuant to the Offer and
approve the Merger Agreement (if required).

     In all cases, payment for Shares accepted for payment pursuant to the Offer
will be made only after timely receipt by the Depositary of (1) the Share
Certificates or confirmation (a "Book-Entry Confirmation") of a book-entry
transfer of such Shares into the Depositary's account at The Depository Trust
Company (the "Book-Entry Transfer Facility") pursuant to the procedures set
forth in Section 3 (Procedures for Accepting the Offer and Tendering Shares) of
the Offer to Purchase, (2) the Letter of Transmittal (or a facsimile thereof),
properly completed and duly executed, with any required signature guarantees or,
in the case of a book-entry transfer, an Agent's Message (as defined below) in
lieu of the Letter of Transmittal and (3) any other documents required by the
Letter of Transmittal. Accordingly, payment may not be made to all tendering
stockholders at the same time depending upon when certificates for Book-Entry
Confirmations into the Depositary's account at the Book-Entry Transfer Facility
are actually received by the Depositary. UNDER NO CIRCUMSTANCES WILL INTEREST BE
PAID ON THE OFFER PRICE TO BE PAID BY THE PURCHASER, REGARDLESS OF ANY EXTENSION
OF THE OFFER OR DELAY IN MAKING SUCH PAYMENT.

     If holders of Shares wish to tender Shares to the Purchaser in the Offer,
but it is impracticable for them to forward their Share Certificates or other
required documents prior to the Expiration Date or to comply with the book-entry
transfer procedures on a timely basis, a tender may be effected by following the
guaranteed delivery procedures specified in Section 3 (Procedures for Accepting
the Offer and Tendering Shares) of the Offer to Purchase.

     The Purchaser will not pay any fees or commissions to any broker or dealer
or other person (other than the Depositary and the Information Agent as
described in the Offer to Purchase) for soliciting tenders of Shares pursuant to
the Offer. The Purchaser will, however, upon request, reimburse you for
customary mailing and handling costs incurred by you in forwarding the enclosed
materials to your customers.

     The Purchaser will pay or cause to be paid all stock transfer taxes
applicable to its purchase of Shares pursuant to the Offer, except as otherwise
provided in Instruction 6 of the Letter of Transmittal.


     WE URGE YOU TO CONTACT YOUR CLIENTS AS PROMPTLY AS POSSIBLE. PLEASE NOTE
THAT THE OFFER AND WITHDRAWAL RIGHTS WILL EXPIRE AT 12:00 MIDNIGHT, NEW YORK
CITY TIME, ON WEDNESDAY, DECEMBER 11, 2002, UNLESS THE OFFER IS EXTENDED.
