VOIP Subscribers Can Lower Costs Using Vanguard Routers
and Add SIP Phones

Vanguard Networks announces new SIP (session initiation protocol) gateway
to allow customers to reap the benefits of IP Telephony. With the addition of
SIP functionality Vanguard customers who subscribe to VOIP services from an IP
telephony service provider will now be able to save on monthly charges, while
keeping high quality and reliability. Customers can continue to use existing
phones connected to a Vanguard Gateway router to keep initial expenses low, and
also add SIP phones to lower administrative costs.

Vanguard Networks provides voice over IP with SIP, QoS, Security & Routing
in a single platform to:

— Allow Internet Telephone Service Providers (ITSP) to offer
single edge device

Vanguard Networks routers support both SIP and analog phones, and corporate
PBX and key systems, supporting a full mix of data and telephony services as
networks evolve.

With this announcement, Vanguard Networks routers now act as a Media
Gateway and a Signaling Gateway between Voice over Frame Relay service and VOIP
service. This powerful feature enhances the abilities of Voice over Frame Relay
customers to migrate to VOIP on their own timeline. Mixed networks of Voice
over Frame Relay sites and Voice over IP sites can easily interoperate.
