Configuring the Catalyst 4000 AGM
In order to provision DSP resources for conferencing and transcoding,
you must configure the AGM for IP telephony gateway mode. You
must first set up the Access Gateway module in Cisco CallManager as
an H.323 gateway with H.225 device protocol. For more details on configuring
Cisco gateways in CallManager, see www.cisco.com/univercd/

Catalyst 6000 Modules
The Cisco WS-6608-T1/E1 module for Catalyst 6000 offers similar functionality
as the Catalyst 4000 AGM.The Catalyst 4000 AGM is intended to be implemented
at the remote or branch office environment and the Catalyst 6000 Voice
T1/E1 and Services module is targeted at the central office or headquarters level
environments.The Catalyst Voice T1/E1and Services module provides Digital T1
or E1 PSTN and PBX gateway services, transcoding, and conference bridging.
The Voice T1/E1 and Services module has eight T1 or E1 ports which support
common channel signaling (CCS) or ISDN PRI signaling. Each port can be
configured as a PSTN/PBX gateway, MTP transcoder, or a conference bridge.

Next, you must set up the switch to communicate with the
CallManager and set the IP precedence. The following is an example of
the necessary steps:
Cat4K_AGM(config)# voicecard sccp manager 192.168.10.250
port 2000
Cat4K_AGM(config)# voicecard sccp local g0/0
Cat4K_AGM(config)# voicecard conference ip-precedence
Configuring the AGM as a Conference Bridge requires some configuration
on the module before it is configured in CallManager. You will
need the MAC address in order to complete the configuration in
CallManager. This can be obtained by entering the following command:
Cat4K_AGM# show voicecard conference
Conferencing:(mac address 00e0.dbef.4863.93e9) Disabled
Once you have the MAC address of the Catalyst 4000 AGM, complete
the steps of setting up a conference bridge in the CallManager
Administration program. For more detailed steps for this process see
www.cisco.com/univercd/cc/td/doc/product/voice/c_callmg/3_1/sys_ad/
adm_sys/ccmcfg/b04cnbrg.htm.
Keep in mind, the Catalyst 4000 must be in gateway mode. This can
be accomplished by entering either or both of the following commands:
Cat4K_AGM(config)#voicecard conference ;Enable conferencing
Cat4kagm(config) #voicecard transcode ;Enable Transcoding
