General Bandwidth Adds SIP-Based IP Centrex to G6 Gateway

General Bandwidth has added full SIP and PRI support within its G6 Packet Telephony Migration Platform. The G6 platform can now be used in conjunction with a SIP feature server to provide a wide range of traditional Centrex and other messaging capabilities. New features can include advanced call screening, single number service, click-to-call, dial from directories, voice & email integration, as well as legacy Class 5 and other new services.


General Bandwidth's G6 platform already offered support for derived voice services from legacy Class 5 switches through GR-303/TR-008 and V5.2 interfaces. Carriers now have the capability to simultaneously deploy VoIP services from the same G6 platform while supporting calls from multiple softswitches and features servers. The G6 software also includes support for RFC2833 with Named Telephony Events (NTE) enabling full Class 5 feature capabilities over VoIP such as voice mail indicator and flash hook-based features as well as support for low bit rate codecs such as G.729e to provide better bandwidth utilization across the carrier's network.
