Partnership solidifies market-leading suite of signaling solutions

ROCHESTER, New York and FRISCO, Texas, January 12, 2011 - PT (Nasdaq: PTIX), a leading global provider of advanced network
communications solutions, and GENBAND, the market share leader in IP voice
solutions, today announced a multi-faceted development agreement to further
advance each company's signaling technology and solutions.

As part of the alliance, the two companies have entered into a long-term
agreement under which PT will provide GENBAND with development, support and
maintenance of signaling solutions as integral elements of GENBAND's premier
switching portfolio. In addition, PT has acquired specific signaling assets
from GENBAND that include the Universal Signaling Point (USP) and SP2000
products and related intellectual property rights.

"Both GENBAND and PT are leaders in IP-based technology, and we welcome
them as a strategic partner," said John Slusser, President and CEO of PT.
"GENBAND's purchase of Nortel's switching assets has preserved many years of
respected research and development, which included significant advancements
in signaling. Now we blend that with over thirty years of PT's innovation and
expertise. This partnership positions both companies to offer the greatest
possible signaling value and performance to our carrier customers."

"GENBAND is continuously focused on the future and forward-looking
technology," said Charlie Vogt, Chief Executive Officer of GENBAND. "This
