Ladies and Gentlemen:

     We have acted as counsel to Genesys Telecommunications Laboratories, Inc.,
a California corporation  (the "Company"), in connection with its registration
of an aggregate of 207,500 shares of its common stock (the "Shares"), which may
be offered for resale by certain stockholders of the Company (the "Selling
Stockholders"), as described in the Company's Registration Statement on Form S-
3, filed with the Securities and Exchange Commission under the Securities Act of
1933, as amended (the "Registration Statement").

     This opinion is being furnished in accordance with the requirements of Item
16 of Form S-3 and Item 601(b)(5)(i) of Regulation S-K.

     We have reviewed the Company's charter documents and the corporate
proceedings taken by the Company in connection with the issuance and sale of the
Shares.  Based on such review, we are of the opinion that the Shares have been
duly authorized, and if, as and when issued in accordance with the Registration
Statement and the related prospectus (as amended and supplemented through the
date of issuance) will be legally issued, fully paid and nonassessable.

     We consent to the filing of this opinion letter as Exhibit 5.1 to the
Registration Statement and to the reference to this firm under the caption
"Legal Matters" in the prospectus which is part of the Registration Statement.
In giving this consent, we do not thereby admit that we are within the category
of persons whose consent is required under Section 7 of the Act, the rules and
regulations of the Securities and Exchange Commission promulgated thereunder, or
item 509 of Regulation S-K.

     This opinion is rendered as of the date first written above and we disclaim
any obligation to advise you of facts, circumstances, events or developments
which hereafter may be brought to our attention and which may alter, affect or
modify the opinion expressed herein.  Our opinion is expressly limited to the
matters set forth above and we render no opinion, whether by implication or
otherwise, as to any other matters relating to the Company or the Shares.



                                    Very truly yours,

                                    BROBECK, PHLEGER & HARRISON LLP


                                    By: /s/ BROBECK, PHLEGER & HARRISON LLP
