PARIS -- CIRPACK, a leading vendor of next generation voice switches for operators' infrastructures, today announced general availability of its SIP Gateway solution for telecom operators deploying voice services over IP local loops and for carriers migrating their transit networks to IP. Cirpack G16S SIP Gateway is a highly scalable carrier-class platform converting voice traffic and signaling between the legacy circuit-based PSTN and next generation IP-based networks using SIP signaling. It is a key infrastructure component to enable public telephony over IP. It can be used to transfer VoIP traffic from SIP subscribers to PSTN destinations, as well as to connect legacy TDM local loops to IP transit networks. Based on Cirpack's field-proven public telephony switches, Cirpack G16S SIP Gateway can host a large variety of high density net-work interface boards, supports nearly all signaling protocols variants and offers advanced routing features. Carriers migrating their transit network to IP will also benefit from transparent transport of legacy ISDN and SS7 signaling over IP to maintain TDM voice services and local exchange switches when upgrading their core backbone to IP technologies. "SIP signaling is gaining increased momentum with telecom service providers, both for delivering VoIP services to subscribers and to build IP-based transit networks," explains Frederic Potter, Cirpack's CTO and Senior VP. "Cirpack's support for SIP signaling is a great addition to our range of Local Exchange and Transit switches. It allows operators to deploy toll-grade VoIP services at a very low cost and to easily migrate their voice backbone to IP. With Cirpack's public telephony switches, operators can connect all their local loops together to the same switching platform and deliver similar voice services to all for increased profitability."
