Release Notes for Cisco CallManager Release 3.0(10)
78-13493-02
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
