Business Wire

ENGLEWOOD, Colo. -- October 24, 2013

Nexmo, a pioneer in cloud-based applications for OTT providers, and CSG
Systems International, Inc. (NASDAQ: CSGS), a global provider of interactive
transaction-driven solutions and services, today announced that Nexmo has
expanded its relationship with CSG to include CSG Assure for fraud protection
and quality assurance.

CSG Assure enables some of the biggest and best-known global communication
services providers to test for and guarantee quality of service. CSG Assure’s
network covers 420 mobile networks in 130 countries, which helps Nexmo verify
the worldwide delivery of time- and content-critical SMS on behalf of its
rapidly growing corporate customer base.

“CSG Assure is like an insurance policy for our existing customers, all of
whom require SMS in real time with appropriate content,” said David Vigar,
director of carrier relations at Nexmo. “We have a culture of customer focus
and innovation that calls for scalability and flexibility to match the
exploding expectations of our growing customer base.”

Nexmo uses CSG Assure as an independent test platform that allows it to
proactively send test SMS through various routes. Mobile operators and SMS
aggregators can then verify results that include precise delivery time,
textual content verification, address verification, character set validation,
concatenated messages delivery testing, and binary content verification.

“SMS aggregators are managing an increasing amount of SMS traffic around the
world, and our SMS testing capabilities are unparalleled,” said George Fraser,
vice president of Europe, the Middle East, and Africa at CSG. “CSG Assure has
become the de-facto standard for SMS testing in the industry; the timely and
relevant content we provide allows our clients to maintain competitive
differentiation while investing in innovation.”

CSG Assure is available in the cloud and as a subscription-based model that
supports speed-to-market for new offerings and seamless hardware and software
updates. Nexmo also benefits from fraud protection, quality assurance, and
increased operational speed and efficiency. In addition to reducing manual
error-prone tasks, Nexmo will be able to adapt in near-real-time to events
such as quality dips to protect its margins and service levels.
