Service provider VoIP gateways are high density, stand-alone appliances offering concurrent use of ISDN, SS7, CAS (R2), SIP, and SIGTRAN signaling protocols all in one package, which lowers costs by eliminating the need for third party media gateway controllers or protocol converters.
They help mobile and wireline service providers add new Value-Added Services (VAS) quickly and provide a clear migration path to an all-IP network.
