ITG-7004

SIP-Based ISDN PRI Gateway

The ITG-7004, SIP-Based ISDN PRI Gateway, gives the NGN-Cored Fixed-Line Operators and large enterprise unprecedented value in a high-function gateway. The ITG-7004 is designed to provide connectivity between PSTN and carrier VoIP networks or enterprise private VoIP SIP-based networks. The ITG-7004 is interop-proven with
commonly deployed central office and SIP-based telephony servers.

High performance voice-processing capability is the most important requirement and measurement for all VoIP gateways. The ITG-7004 configured with one to four ISDN PRI E1/T1 interfaces can process up to 120 simultaneous VoIP and/or FoIP calls without concentration. The Gateway Card embeds powerful DSP technology to support G.711,G.729A, G.723, G.168 echo cancellation, DTMF relay RFC2833, and T.38 fax relay.
