Voice over Internet Protocol with Avaya

J2320, J2350, J4350, and J6350 Services Routers support voice over IP (VoIP) connectivity for branch offices with the Avaya IG550 Integrated Gateway. The Avaya IG550 Integrated Gateway consists of four VoIP modules—a TGM550 Telephony Gateway Module and three types of Telephony Interface Modules (TIMs).

The VoIP modules installed in a Services Router at a branch office connect the IP and analog telephones and trunk lines at the branch to headquarters and to the public-switched telephone network (PSTN).

You can use either J-Web Quick Configuration or a configuration editor to configure VoIP on the Services Router. Alternatively, you can download a complete router configuration that includes VoIP from an Electronic Preinstallation Worksheet (EPW) and a Disk-on-Key USB memory stick.

For information about which devices support the features documented in this chapter, see the JUNOS Software Feature Support Reference for SRX Series and J Series Devices.
