I have a situation where all the phones within a specific calling search space and device pool are unable to participate in conference calls. This has ever been the case for this remote site. The devices are configured to use the default Built in Bridge as are all the other remote sites, which all enjoy conference calling ability. The router seems to be configured the same as the other remotes as well. I am running CUCM 7.1.3 with 2821 gateways at the remote sites. Anyone have a good idea on this one? Thanks.
