Item 1.01 Entry into a Material Definitive Agreement.

CSG Systems International, Inc. (“CSG”) generates a significant portion of its revenues from EchoStar Communications (“EchoStar”) under a multi-year processing agreement. On December 1, 2005, CSG issued a press release announcing that it had signed a new multi-year Master Subscriber Management System Agreement (the “Agreement”) with EchoStar to continue providing customer care and billing support services to EchoStar. A copy of such press release is attached to this Form 8-K as Exhibit 99.1 and is incorporated into this section by reference.

The key terms of the Agreement are as follows:

• The Agreement is effective November 1, 2005, and runs through the end of December 2008. The previous processing agreement with EchoStar was scheduled to expire in March 2006.

• The Agreement provides EchoStar with the option to extend the term of the Agreement for either one or two years beyond the end of December 2008.

• The Agreement does not provide CSG with the exclusive right to provide customer care and billing services to EchoStar, which differs from the previous processing agreement with EchoStar.

• The Agreement includes certain financial commitments from EchoStar such that if EchoStar terminates the Agreement before expiration for reasons other than cause, the balance of the financial commitments will be due CSG.

• The fees for certain processing services provided under the Agreement were reduced on a per unit basis when compared to the previous processing agreement with EchoStar.

As noted above, the Agreement provided certain pricing reductions when compared to the previous processing agreement with EchoStar. However, based upon CSG’s expectation of continued growth in the number of Echostar’s customers processed on CSG’s systems, and CSG’s expectation of selling a historically consistent amount of new products and services to EchoStar under the Agreement, CSG expects total revenues generated from EchoStar in 2006 will not differ materially from that of 2005.

Although the new pricing under the Agreement was effective November 1, 2005, CSG does not expect the new Agreement to have a material impact to CSG’s overall expected financial performance for the fourth quarter of 2005.

This report contains forward-looking statements as defined under the Securities Act of 1933, as amended, that are based on assumptions about a number of important factors and involve risks and uncertainties that could cause actual results to differ materially from what appears in this report. Some of the risks and uncertainties that are foreseen by management are contained in Exhibit 99.01 “Safe Harbor for Forward-Looking Statements Under the Private Securities Litigation Reform Act of 1995--Certain Cautionary Statements and Risk Factors” in CSG’s most recent Form 10-Q for the quarter ended September 30, 2005. Readers are strongly encouraged to review this exhibit closely in conjunction with this report.

Item 7.01 Regulation FD Disclosure.

On December 1, 2005, CSG Systems International, Inc. issued a press release announcing that it had signed the Agreement with EchoStar. A copy of such press release is attached to this Form 8-K as Exhibit 99.1 and is incorporated into this section by reference.

We are pleased that EchoStar has demonstrated its commitment and its appreciation to CSG with this three-year extension.”

CSG began providing customer care and billing support to EchoStar in 1996, when the company first launched digital satellite service in the United States. Since that time, CSG has built a comprehensive team to support EchoStar’s day-to-day needs and to assist with ongoing strategic initiatives relating to billing and customer care.

“CSG is a trusted and valued partner of EchoStar’s,” said Rob Strickland, senior vice president and chief information officer at EchoStar. “CSG has been instrumental in our ability to continually provide the highest quality service to our customers and has a tremendous understanding of our business.
