7937 on a CUCM 6.0: No DTMF

Unanswered Question
Mar 10th, 2009

I've got a 7937 IP Conference phone connected on a CUCM 6.0 server. The phone works fine when calling to/from extensions as well as outbound/inbound calls. However, after an outbound call is initiated it will not pass the DTMF tones so it can't enter pins for conference bridges, etc.

Any ideas?

I have this problem too.
