Item 3.  Incorporation of Documents by Reference.
         ---------------------------------------

     The following documents filed with the Securities and Exchange Commission
(the "Commission") are hereby incorporated by reference:
      ----------

     (1) The Company's Annual Report on Form 10-K for the year ended
         December 31, 1998;

     (2) The Company's Quarterly Reports on Form 10-Q for the quarters ended
         March 31, 1999, June 30, 1999 and September 30, 1999;

     (3) The Company's Current Report on Form 8-K filed with the Securities and
         Exchange Commission on January 19, 1999; and

     (4) The description of the Company's capital stock contained in its
         Registration Statement on Form 8-A as filed with the Commission on
         March 22, 1990, including any amendment thereto or report filed for the
         purpose of updating such description.

     All the documents filed by Registrant pursuant to Sections 13(a), 13(c), 14
and 15(d) of the Exchange Act after the date hereof, and prior to the filing of
a post-effective amendment which indicates that all securities offered hereunder
have been sold or which deregisters all securities then remaining unsold under
this registrations statement, shall be deemed to be incorporated by reference

Item 4.  Description of Securities.  Not applicable.
         -------------------------

Item 5.  Interests of Named Experts and Counsel.  Not applicable.
         --------------------------------------

Item 6.  Indemnification of Directors and Officers.
         -----------------------------------------

   Section 317 of the California Corporations Code allows for the
indemnification of officers, directors, and other corporate agents in terms
sufficiently broad to indemnify such persons under certain circumstances for
liabilities (including reimbursement for expenses incurred) arising under the
Securities Act of 1933, as amended (the "Securities Act").  Article IV of the
Registrant's Articles of Incorporation and Article VI of the Registrant's Bylaws
provides for indemnification of the Registrant's directors, officers, employees
and other agents to the extent and under the circumstances permitted by the
California Corporations Code.  The Registrant has also entered into agreements
with its directors and officers that will require the Registrant, among other
things, to indemnify them against certain liabilities that may arise by reason
of their status or service as directors to the fullest extent not prohibited by
law.  In addition, the Registrant carries director and officer liability
insurance in the amount of $20 million.

Item 7.  Exemption from Registration Claimed.  Not applicable.

  Item 9.  Undertakings.
           -------------

   The undersigned Registrant hereby undertakes:

           (1) to file, during any period in which offers or sales are being
made, a post-effective amendment to this registration statement to include any
material information with respect to the plan of distribution not previously
disclosed in the registration statement or any material change to such
information in the registration statement.

           (2) that, for purposes of determining any liability under the
Securities Act, each such post-effective amendment shall be deemed to be a new
registration statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof.

           (3) to remove from registration by means of a post-effective
amendment any of the securities being registered which remain unsold at the
termination of the offering.

     The undersigned Registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act, each filing of the
Registrant's annual report pursuant to Section 13(a) or Section 15(d) of the
Exchange Act that is incorporated by reference in the registration statement
shall be deemed to be a new registration statement relating to the securities
offered therein, and the offering of such securities at that time shall be
deemed to be the initial bona fide offering thereof.

     Insofar as the indemnification for liabilities arising under the Securities
Act may be permitted to directors, officers and controlling persons of the
Registrant pursuant to the foregoing provisions, or otherwise, the Registrant
has been advised that in the opinion of the Commission such indemnification is
against public policy as expressed in the Securities Act and is, therefore,
unenforceable.  In the event that a claim for indemnification against such
liabilities (other than the payment by the Registrant of expenses incurred or
paid by a director, officer or controlling

                                      -4-


person of the Registrant in a successful defense of any action, suit or
proceeding) is asserted by such director, officer or controlling person in
connection with the securities being registered hereunder, the Registrant will,
unless in the opinion of its counsel the question has already been settled by
controlling precedent, submit to a court of appropriate jurisdiction the
question of whether such indemnification by it is against public policy as
expressed in the Securities Act and will be governed by the final adjudication
of such issue.

                                      -5-


                                   SIGNATURES

     Pursuant to the requirements of the Securities Act of 1933, the Registrant,
Aspect Communications Corporation, a corporation organized and existing under
the laws of the State of California, certifies that it has reasonable grounds to
believe that it meets all of the requirements for filing on Form S-8 and has
duly caused this Registration Statement to be signed on its behalf by the
undersigned, thereunto duly authorized, in the City of San Jose, State of
California, on November 24, 1999.
