Second, check the maximum number of users configured in the conference (Ad Hoc or Meet-Me) to determine if the problem occurred because this number was exceeded.

Transcoding Problems

If you have installed a hardware transcoder in the Cisco Catalyst 6000 8 Port Voice T1/E1 and Services Module, and it doesn’t work as expected (meaning you cannot make calls between two users with no common codec), check to see if you have any available Transcoder resources registered with Cisco CallManager (must be hardware). Use Microsoft Performance to check the number of “MediaTermPointsAvailable” available.

One E1 port (WS-X6608-E1 card contains 8x E1 ports) provides Transcoder/MTP resources for 16 calls, as shown in the following trace.
