Cirpack Introduces Carrier-Class SIP Gateway for Public Telephony over IP

CIRPACK announced commercial 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 converts voice traffic and signaling between the PSTN and IP networks by using SIP. It can handle up to 1024 RTP channels with echo cancellation per interface board and convert VoIP/RTP traffic to TDM circuits or ATM cells to connect service providers' IP infrastructures to any other local loops and core backbones. It also supports nearly all voice signaling protocol variants (SS7/ISUP, ISDN, VoATM) and offers advanced Class-4 routing features. Cirpack said its SIP Gateway is currently deployed in field trails with various European telecom service providers. Several SIP Phones and CPEs from vendors such as Cisco Systems, D-Link, Innomedia, Pingtel, Snom AG and others have been fully certified for full interoperability.
