I just upgraded to CM 5.1 from 4.1.3. After the upgrade, my IOS sccp conference bridges will not register. Looking at the cm interface, it states that the registration is rejected.
From the router I see:
Conferencing Oper State: ACTIVE_IN_PROGRESS - Cause Code: CCM_REGISTER_FAILED
Thanks in advance...
I assume you have matched the profile name under the sccp ccm group with that in Call Manger and they match. Try removing the version in the sccp ccm lines. I have found the version is not needed and leave it out so that thing will still work after upgrades. You said you upgraded to Call Manager 5.1, but have version 5.0.1 listed.
