NORTEL NETWORKS : Turk Telekom Takes Up Nortel Solution for Delivering IP Powered Business Communication Services

Reaching Out to Corporate and SMBs with New Centrex IP and SIP
Multimedia Services

ISTANBUL, TURKEY--(Marketwire - October 09, 2008) - Turk Telekom has
selected a Nortel(1) (TSX: NT)(NYSE: NT) IP Powered Business
communications solution to unlock opportunities for new service
revenue by providing carrier-grade voice and multimedia services to
businesses and consumers throughout Turkey. The new solution enables
Turk Telekom to deliver Centrex IP and SIP multimedia services to
corporate customers and small to medium-sized businesses (SMBs)
without having to invest in new infrastructure.

Building on its long-term relationship with Turk Telekom, which
includes its next-generation network (NGN) international gateway
deployed in 2003, Nortel is now expanding its cooperation with
Turkey's number one carrier to include delivery of SIP applications
for corporations and SMBs.

"Our relationship with Turk Telekom spans four decades during which
Nortel has consistently proven its ability to design, deploy, and
support some of the world's most reliable networks," said C. Mujdat
Altay, president, Nortel Netas. "With its latest IP powered services
deployment, Turk Telekom's corporate customers will be able to
benefit from the latest VoIP and multimedia technology via wireless
or wireline networks according to their unique needs. As fixed-line
and mobile calls are managed by the same network, Turk Telekom can
offer simple and more affordable services that will increase personal
productivity and allow more focus on their business."

Nortel's VoIP Infrastructure solutions, products and services deliver
fully-featured, carrier-grade telephony, data and multimedia services
over multi-service packet networks. The customized VoIP solution for
Turk Telekom is based on the Nortel Communication Server (CS) 2000,
the market leading IP Multimedia softswitch that supports a wide
range of voice and multimedia business features and industry-standard
VoIP protocols. Due to its strategic architecture including
consolidated local, tandem and long distance capabilities the Nortel
solution enables Turk Telekom to cost-effectively transition to an IP
network, without needing to invest in overlay solutions. It also
provides a comprehensive, expandable voice feature set for
residential and business customers and the ability to reduce
operational expense by up to 30 percent and capital expense by up to
50 percent.

The end-to-end solution also includes customer premise equipment
(CPE) for end users, including Nortel SIP phones and the Nortel
Business Services Gateway (BSG). The BSG is an advanced SMB router
which integrates in one box routing, switching, mobility, security,
quality of service (QoS) and SIP gateway capabilities for voice and
data services. These new capabilities include SIP Mobility extensions
to integrate Turk Telekom's GSM and hosted VoIP environments.

This Mobile Extension service gives workers the ability to connect
mobile phones into their company's corporate network allowing
business travelers to use the same phone functionality and services
such as short dialing and single voicemail wherever they are, whether
they are on their mobile or desk phone. Services from Nortel's Global
Services portfolio such as service development support for
click-to-call functionality are also included in the solution for
Turk Telekom.

Nortel provides VoIP and multimedia solutions to many of the world's
leading service providers, including Bell Canada, Rogers
Communications, SaskTel, Telus, Verizon, Embarq, Verizon Business,
British Telecom, Cable & Wireless and Neuf Cegetel. According to
Dell'Oro Group, Nortel is the worldwide leader in carrier VoIP and
has maintained that position for the last six years (2002-2007).
Also, Gartner positions Nortel in the enviable Leader's quadrant of
its Magic Quadrant (MQ) for Softswitch Architecture, 2008. Nortel has
deployed over seven million SIP lines and has shipped more than 95
million carrier VoIP ports to more than 300 carriers globally.
