I am having an issue integrating our MCU / CUVCM with our Call Manager. I can make calls from Call Manager to the MCU, but from the MCU back to the Call Manager does not work. The MCU can call other h323 endpoints that are registered to our Cisco IOS h323 gatekeeper. Some background:
CUVCM (latest version)
3515 MCU (h323 registers with CUVCM internal gatekeeper)
IOS H323 Gatekeeper (2 zones, config below)
Single Call Manager cluster with 50 remote sites, 1000 phones, 6 digit extensions (leading 2 digits are different at every site)
Call Manager has an h225 trunk to the gatekeeper, is registered, and I can place calls to the MCU and start a conference. However, the MCU cannot dial out to invite people. I would be happy with the MCU dialing a 6 digit extension, but it can't even do that. First time with h323 gatekeeper so I probably have it all wrong, but the config is below.
10.10.8.40 - IOS h323 gatekeeper
10.10.4.69 - CUVCM server
10.10.8.101 - Call Manager Subscriber
205... - Service prefix on my MCU
...... - represents the 6 digit extensions of all the IP Phones connected to our Call Manager
zone local ccm domain.com 10.10.8.40
zone remote cuvcm domain.com 10.10.4.69 1719
zone prefix cuvcm 205...
zone prefix ccm ......
gw-type-prefix ...... gw ipaddr 10.10.8.101 1720
server registration-port 20000
Any help would be appreciated.
