ENGLEWOOD, Colo. -- November 19, 2013

CSG International, Inc.(NASDAQ: CSGS), a global provider of interactive
transaction-driven solutions and services, today announced that it has been
named as a finalist for the “Best LTE Traffic Management Product” by Informa
Telecoms & Media. The winner will be announced during the 2013 LTE North
America Awards in Dallas later this month.

CSG Intermediate 7 was selected as a result of its performance for a
market-leading wireless operator with more than 46 million subscribers. CSG
Intermediate 7 processes 19 billion voice and data transactions every day for
this operator at throughput rates of more than 46,000 transactions per second.
The solution has enabled marked improvements in enterprise operations and
business processes with no loss of billable data. It has enabled the operator
to consolidate to a single high-performance platform across its services and
market segments, reducing the need for continual hardware and software
investments.

“We have seen robust demand across all of our markets for next-generation
traffic management solutions that collate complex network records, prioritize
them, and process them intelligently,” said Jennifer Fellows, vice president
of product management at CSG. “As organizations struggle to address the
enormous charging volumes LTE generates, Intermediate 7 offers them an
optimal—and proven—solution. Operators around the world can now
cost-effectively manage their network assets and the events that flow across
them without sacrificing the customer experience or delaying time-to-profit of
new services.”

The LTE North America Awards recognize organizations for innovation and for
contributions to the future of mobile broadband; the Best LTE Traffic
Management Product category celebrates excellence in LTE deployments. Winners
will be announced during the LTE North America 2013 Awards on November 21,
2013 at the Westin Galleria in Dallas.
