Hi Expert!
I'm running CUCM 9.0. I have Software Conference Bridge build-in which are added to MRG->MRGL-Device pool and Phones. My Region has been set to G.711. All IP Phones and Conference Bridges are associated with the same Device pool. I just need an internal conference, no PSTN, no outside call, but I can't. The symptom is that the phone said "Conference" but return Fast Busy tone. Same as Meet Me. All of my phones are registering to same CCM server.
The RTMT tells that The Resource is unavailable.
Can you help me to solve the problem?
Thanks
