Juniper J2320, J2350 J4350 and J6350 routers support Avaya's IG550 Media Gateway–a set of plug-in modules that offers media gateway capabilities and a variety of traditional telephony interfaces for analog, digital and ISDN trunks, as well as analog and IP stations. The IG550 Media Gateway works with the Avaya S8400, S8500 and S8720 Media Servers running Avaya Communications Manager 4.0 to extend rich communications applications transparently to the branch from centralized locations. The IG550 media gateway also offers customers protection from business critical communications interruptions at the branch by offering a range of survivability options, enabling increased availability under a variety of network conditions up to and including complete loss of WAN connectivity.
