Conference between CUCM 8 and CME

Jean Lofrano · ‎02-10-2012

Hi voice team!

I have a CUCM (site A) with conference bridge working properly to internal calls and with another site C using CME.

But, the conference between CUCM (site A) and CME (site B) is not working...

The Site B configuration is bellow:

Then the CME configuration is irrelevant here as the issue is on CUCM side, are you using hardware or software bridge?

If software then what is the region between the CME trunk and the phone (what codec is defined) as you may need transcoders if G729 is defined due to the fact that software conference bridge only supports G711.
