CallManager and 2851 T-1 PRI

I am having a strange issue with my CallManager and 2851 Router with a T-1 PRI connection to the PBX. Users can dial into the VOIP network and dial out to the PBX no problem but when they enter voice mail or MeetingPlace and enter digits they are duplicated. For example if you dial into MeetingPlace and it prompts you for a meeting ID and you enter 1234, MeetingPlace receives 11223344. Any ideas on what maybe causing this?

Hi Rick,

if possible, please upgrade to the latest 12.4.20T image to avoid running into the following defects whose symptoms are similar to what you describe:

CSCso92891 - DTMF Digits not properly detected

CSCso87127 - DTMF leakage of 40-50msec observed

Hope this helps.

Regards,

Michael.
