WOKING, England & ENGLEWOOD, Colo. -- May 14, 2013

CSG International (NASDAQ: CSGS), a global provider of software- and
services-based business support solutions that help clients generate revenue
and maximize customer relationships, today announced that ALBtelecom has
implemented CSG Interconnect® as its wholesale billing management solution for
its fixed line business and mobile brand, Eagle Mobile.

As Albania’s leading operator with subscriber numbers rapidly approaching one
million, an increasing number of calls extend from ALBtelecom’s networks to
those of other domestic and international operators, or commence on other
networks and terminate on those of ALBtelecom.

ALBtelecom implemented CSG Interconnect to automate partner management,
carrier-to-carrier rating, billing and settlement, as well as support dispute
resolution and reconciliation processes.

“In 2011 we invested around 40 million Euros replacing and enlarging our
network across Albania, to prepare our infrastructure for the latest
technology and improve service infrastructure for our subscribers,” said
A.Vahap Yeroglu, deputy CEO of ALBtelecom. “We must of course earn new
revenues to monetize these infrastructure investments and to help fund future
improvements. Carrier-to-carrier billing offers an important and growing
source of income for us and by using CSG Interconnect we expect to settle with
other operators more swiftly and efficiently than before, whilst adding
additional revenue from detecting traffic our previous manual and in-house
developed software approaches might have missed.“

CSG Interconnect is a market-leading wholesale business management solution
handling every kind of network traffic for local, regional and worldwide
operators in a single, highly integrated platform. The solution is part of
CSG’s Wholesale Business Management Solution (WBMS) which provides
highly-efficient partner management, optimized traffic trading and routing
through the network, accurate billing and settlement for all services
including traditional voice, data, IP/content and GSMA roaming services. WBMS
offers a pre-integrated combination of CSG's proven products including its
latest acquisition, Ascade 7, which provides end-to-end process support for
the supply chain of trading and exchanging voice traffic between operators.

“Wholesale partner management, billing and settlement is a core element of any
operator’s cost and revenue model and by optimizing the interconnect process,
significant costs can be saved and new revenues won,” said Mike McKnight, Vice
President of Professional Services, EMEA, CSG International. “With CSG
Interconnect, ALBtelecom has chosen an advanced billing platform that will
easily scale to handle its growing subscriber numbers and expanding traffic,
whilst helping it to fund recent and future investment in its network
infrastructure for the benefit of its customers.”
