                     CSG SYSTEMS INTERNATIONAL, INC. URGES
                             SHAREHOLDERS TO REJECT
                 Unsolicited Tender Offer By Peachtree Partners

Denver, Colorado (July 2, 1999) - CSG Systems International, Inc. (NASDAQ: CSGS)
announced today that it recommends that its shareholders reject an unsolicited,
below-market offer made by Peachtree Partners for up to 1% of CSG Systems
International, Inc.'s outstanding shares.  The $20.50 per share offer is dated
June 16, 1999 and will expire on July 28, 1999.  CSG Systems' management just
recently became aware of the offer as a result of an inquiry from a shareholder.
As the offer indicates, Peachtree Partners is not affiliated in any way with CSG
Systems International, Inc. and Peachtree Partners has had no contact with the
company regarding the offer.  The offer price of $20.50 per share represents a
discount of approximately twenty-seven percent (27%) from yesterday's closing
price of $28.1875 on NASDAQ.  Any CSG Systems' shareholder who desired to sell
his or her shares should therefore be able to obtain a higher price on the
NASDAQ exchange than that offered by Peachtree Partners.

These so-called "mini tender offers" have gained considerable notoriety of late,
including articles appearing in business publications, such as The Wall Street
Journal. Mini tender offers avoid the usual disclosure requirements applicable
to tender offers for more than five percent (5%) of targeted company stock.
These mini tender offers are the subject of a bulletin posted on the Securities
and Exchange Commission's web site entitled "Mini Tender Offers: Beware Of
Offers To Buy Your Securities At Below Market Prices." That bulletin can be
found at the following address:
http://www.sec.gov/consumer/keyword/tminiten.html. CSG Systems encourages its
shareholders to access this site to learn of the Commission's perspective on
these types of offers.
