New and Changed Information

Additional MGCP Support for Cisco VoIP Gateways

Media Gateway Configuration Protocol (MGCP) support provides two primary benefits over H.323 support. First, MGCP provides a centralized dial plan. An H.323 network requires that the dial plan for each gateway be statically configured. Every dial plan change requires updating the dial plan in every gateway. MGCP provides centralized dial plan configuration support at the Cisco CallManager.

Cisco CallManager Release 3.0(5a) adds MGCP support for the following

Cisco VoIP gateways:

•Cisco 2600 Series gateways with FXS and FXO analog interfaces

•Cisco 3600 Series gateways (362X, 364X, 366X) with FXS and FXO analog interfaces

Note At Cisco CallManager Release 3.0(5a), MGCP code support in the 36XX router/gateways was not complete. Once complete and tested, these gateways will be supported in an AVVID network.

Cisco VG200 FXO Hookflash Support

The added Cisco VG200 FXO hookflash support Symbol NetVision Phones, which are configured as H.323 client devices. The Cisco VG200 can be configured to provide hookflash feature support from H.323 NetVision phones through Cisco VG200 FXO ports attached to PBXs. The NetVision Phones issue H.245 messages through the Cisco CallManager to Cisco VG200 FXO gateways on initiation by the user of PBX functions. The Cisco VG200 gateway interprets the signals and translates them to an FXO hookflash followed by a PBX-specific feature code.

AMIS-A Support

Signaling within the Skinny Gateway Control Protocol client and Skinny Gateway stacks in Cisco CallManager has been extended to properly interpret and pass out-of-band equivalent signals for “A,” “B,” “C,” and “D” DTMF signals. These additional signals can be passed from AMIS-A compliant messaging system
