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

    MANSFIELD, Mass., Aug. 30 /CNW/ -- 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
    -- Provide analog/digital phone to SIP gateway capabilities
    -- Provide (FXO) PSTN back up to ITSP service
    -- Support SIP IP-Phones
    -- Route IP and non IP data
    
    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.
