Comverse Solution Tightly Integrates BSS, Mobile Internet,
   and HUB Value-Added Services for Superior User Experience and
                           Cost Savings

WAKEFIELD, Mass., July 5, 2011 (GLOBE NEWSWIRE) -- Guyana Telephone &
Telegraph (GT&T), the incumbent telecommunications service provider in
Guyana, has selected Comverse's flagship converged BSS, Comverse(R)
ONE(TM) Billing & Active Customer Management Solution with Comverse
Mobile Internet, and Comverse HUB Voice & Messaging Value-Added
Services (VAS), to power a significant business transformation that
will enable it to offer unmatched service with significant OPEX
reduction throughout its converged triple play (landline, mobile,
Internet) portfolio.

"Our fundamental drive is to provide our subscribers with superior
service. The way we achieve this in our fast-changing industry is by
continued improvement to our business," said Yog Mahadeo, CEO at GT&T.
"This deployment of solutions from Comverse will position us to provide
a best-in-class communication experience, with agility to dramatically
reduce time to market when launching new services and to grow -- all
while benefiting from tremendous operating cost reductions."

GT&T selected Comverse(R) ONE(TM) to benefit from a single product
catalog and rating engine, efficiently uniting all subscribers (prepaid
and postpaid) and all lines of business (mobile, wireline, Internet).
This makes possible innovative bundles, cross services, real-time
personalized promotions, rewards and more, plus significant operating
cost efficiencies.

Tight integration of Comverse ONE with Comverse(R) Mobile Internet
Hub(TM) promotes mobile data traffic optimization and monetization.
Integration with Comverse HUB VAS solutions such as Next-Generation
Voicemail, SMSC, MMS, and USSD (information over signalling channels)
can advance maximization of voice and messaging assets and
opportunities. This comprehensive robust linkage empowers GT&T to take
full advantage of the synergies between these systems to improve
efficiency, significantly reduce total cost of ownership and accelerate
time to market -- all while improving service and data monetization.
The "out of the box" nature of the linked solutions can dramatically
reduce deployment time and risk.

"Pre-eminent in BSS, mobile Internet and VAS, Comverse offers advanced
technologies that can deliver true business transformation with tightly
linked solutions that ideally provide communication service providers
(CSPs) like GT&T with an edge for success in a competitive market now
and beyond -- into a future of convergence and IPfication." said Lionel
Chmilewsky, Senior Vice President, Head of Customer Facing Group at
Comverse. "It is yet another validation of the value of our close bond
with our customers that GT&T is extending its long-term relationship
with us by choosing Comverse to take their operations to the next
level."

The business transformation at GT&T raises Comverse's already high
profile in Latin America and the Caribbean. With one of the largest
installed bases in the region, Comverse is distinguished as a top BSS
solution provider. Many of the CSPs in the area are migrating to
Comverse ONE to optimize benefit from the tremendous growth in mobile
data.
