CHICAGO, Aug. 2, 2011 (GLOBE NEWSWIRE) -- Neutral Tandem, Inc.,
(Nasdaq:TNDM), a leading provider of global interconnection services,
announced today the expansion of its global network through the
deployment of a PSX voice soft-switch from Sonus Networks in one of the
world's largest interconnection hubs, the Telehouse Docklands North
location in London. The new location offers Neutral Tandem's
international carrier customers the ability to interconnect via TDM or
SIP/IP. The added flexibility makes it easier for carriers to
interconnect and take advantage of Neutral Tandem's innovative voice
termination services such as CommonPoint(R), which helps international
carriers complete calls to tens of millions of wireless and wireline
telephony end points in the United States. In addition, customers can
directly interconnect with the Neutral Tandem global voice network via
SIP\IP in Austria, Belgium, Denmark, France, Germany, Ireland, Italy,
Netherlands, Poland, Spain, Sweden, Switzerland, Hong Kong, Singapore,
Canada, and the United States.

"Deploying a voice soft switch in Telehouse's facility in London
reinforces our ongoing commitment to expand our International Voice
Services, and provides scalable, high quality, direct termination for
our carrier customers," said Edward Evans, CEO of Neutral Tandem. "This
deployment is yet another milestone attained by Neutral Tandem as we
expand globally and strengthen our fully meshed, all-IP, MPLS network,
and streamline how competitive carriers route traffic between one
another."

"The Telehouse world-class data center in London provides an ideal
location for Neutral Tandem's European customers to interconnect and
route their traffic to the U.S.," stated Michelle Reid, Director of
Telehouse UK. "Additionally, our data center in London provides a
neutral point of interconnection and is a major hub for companies that
operate in the European markets."
