IG550 Integrated Gateway

The IG550 Integrated Gateway is a part of Avaya’s growing solutions for extending Communication Manager communication capabilities from the headquarters of an organization to all collaborative branch locations.The IG550 Integrated Gateway is an H.248 media gateway that combines Avaya’s high-performance telephony and Voice over IP (VoIP) communications with the sophisticated routing capabilities of the Juniper J-Series routers.

The IG550 consists of the TGM550 Telephony Gateway Module (TGM550) and Telephony Interface Modules (TIMs). The IG550 is inserted into either a Juniper J4350 or J6350 Services Router. The IG550 is also connected over a LAN or WAN to an Avaya server running Communication Manager. Therefore, Avaya S8700-series, S8500, S8400, and S8300 Servers are able to provide the same top quality telephony services to the small branch office as to the headquarters of the organization. As a result, the IG550 provides full feature support for IP and analog telephones. See Figure 12.
