Nortel Government Solutions Teams With General Dynamics To Offer Latest In VoIP Secure Telephony

FAIRFAX, VIRGINIA, Jun 16 (MARKET WIRE) --
Nortel Government Solutions (NGS), a U.S. company wholly owned by
Nortel(1) (TSX: NT)(OTCBB: NRTLQ), has been designated by General
Dynamics as an authorized reseller of the General Dynamics Sectera(R)
vIPer(TM)(2) Universal Secure Phone.

"This is an exceptionally beneficial relationship for federal customers,"
said Chuck Saffell, CEO, Nortel Government Solutions. "As federal
agencies and departments streamline inter-agency communication networks
and enhance their unified communications capabilities by migrating to the
use of VoIP, the combination of the Nortel Application Server 5300 with
the General Dynamics Sectera vIPer Universal Secure Phone enables NGS to
provide a secure, end to end VoIP solution for federal government
customers with secure voice communications needs."

The General Dynamics Sectera vIPer Universal Secure Phone provides the
latest upgraded algorithms and Secure Communications Interoperability
Protocol (SCIP) technology. Using SCIP signaling and commercial open
standards, the Sectera vIPer phone enables secure communications over
VoIP and PSTN networks. The vIPer is the only VoIP phone with integrated
security certified to protect information classified Top Secret and
below, including Sensitive But Unclassified (SBU) over commercial
networks, and is available to support multiple key sets for U.S.
government sponsored interoperability (e.g., NATO and coalition).

The combination of the Joint Interoperability Testing Command
(JITC)-certified Nortel AS 5300 software solution and the General
Dynamics vIPer phone enables NGS to provide a secure VoIP capability to
federal government customers - eliminating the need to use multiple
desktop phones in order to accomplish secure and non-secure voice
communications.

The AS 5300 is a Session Initiated Protocol (SIP)-based UC software
solution that provides secure productivity, mobility, conferencing,
messaging, personalization, video and collaborative applications. AS 5300
is currently the only product of its kind to be certified by the
Department of Defense's Joint Interoperability Testing Command. It
provides for secure, standards based, multi-vendor interoperability in a
VoIP environment. This interoperability is what enables the integration
of the advanced, General Dynamics Sectera vIPer Secure Phone into a
complete solution for Federal Government customers.
