J4350 and J6350 Services Routers support voice over IP (VoIP) routing through the Avaya TGM550 media gateway module. The TGM550 works with the Avaya TIM510, TIM514, and TIM521 telephony media modules to connect IP and legacy analog telephones and trunks over IP networks.
The telephony services on the TGM550 are controlled by a Media Gateway Controller (MGC)—an Avaya media server running Avaya Communication Manager (CM) call processing software. The TGM550 is managed by an MGC located at headquarters or in a branch office. When the primary MGC is located at a remote location, the TGM550 uses standard local survivability (SLS) for partial MGC backup in the event that the connection to the primary MGC is lost. This enables the J-series Services Routers to provide the same telephony services to the branch office as to the headquarters of the organization.
You can use either J-Web Quick Configuration or a configuration editor to configure VoIP on the Services Router.
