I'm experiencing problems when trying to use the Meet Me function for a conference call. Whenever I try pressing the Meet Me softkey and dial one of the allocated Meet Me DN's I get an engaged / busy tone.
I am using a software conference bridge and have confirmed that this is selected in the relevant MRG. The conference bridge also appears to be in the correct device pool and using the G.711 audio codec. I have checked that there is no conflict with the Meet Me number range and any existing DN's.
Call Manager version is 6.1.3
Definately sounds like a problem negotiating the codec, assuming that you definately have the IP VMS service running, and shown as 'registered' when you list the conference bridges...
Otherwise your MRGs may not be correct...
If you aren't convinced, a good rough test to verify that your regions etc are at fault is to move the conf device into the same device pool as the three phones you are testing the conference with, reset the conference bridge, and try the ad-hoc conf (the intra-region default coded is G711, unless you have changed this - verify by dialling between the two phones and hitting ??)
If that doesn't work, then move the conf bridge you want to use out of any MRGs that it is a member of. In the partition it's available for use by any device.
