[cisco-voip] Call Manager Groups

[Matthew Saskin]

What CallManager locations are your conference bridges (either hardware or
software) registered to?  Just based on your description, I'd look at the
working and broken cases and determine (a) the location that your phones are
in, (b) the location your conference bridge is in, and determine if you've
got a location-based call admission control issue
