Intelligent Voice
Gateway
Serving as the foundation
of sentitO’s Open Network Xchange
(ONX) architecture, the award-winning IVGTM
combines a VoIP media gateway with call
control logic to help global service providers
roll out Voice over IP services and transport
across their entire customer base in less
time, with less money and with better quality
and reliability than their competitors.
The IVG is the ideal solution
for carriers with growing businesses who
no longer wish to "rack and stack"
lower-density voice gateways, but who also
don't require higher-density switching solutions.
Carriers can begin with ISDN PRI connections
and then move to lower-cost SS7 IMT connections.
The IVG provides application flexibility
in a highly-scalable platform.
The IVG scales from 16 to
192 T1s (12 to 144 E1s) in a single chassis
and supports up to 4608 concurrent calls
across its 120 Gbps switch fabric. A standard
7' rack supports up to 13,824 simultaneous
calls.
The IVG™ is more than
a carrier-class VoIP gateway. It is a highly-scalable
platform designed for successful market
defense and expansion.
Only the IVG with ElasticEdge™ technology
provides open, SIP- based control of SS7
IMT and ISDN PRI interfaces. Service providers
can add feature server, billing servers
and session border controllers and immediately
provide wholesale longdistance, calling
card, and other voice services over a single
IVG. In short, the IVG ensures voice application
and revenue diversity beyond the competition.
The IVG is purpose-built
for carrier-class VoIP deployments. The
NEBS and TSIcompliant IVG delivers hot-swappable
modules, 1:N redundancy on all gateway cards
and 1:1 redundancy on all network cards.
The IVG provides enhanced QoS mechanisms
and can be counted on to deliver unparalleled
reliability while delivering multiple carrier
VoIP applications throughout distributed,
global deployments.
