Quick question, we just got a 7937 conference phone. When we dial a specific number we have the call go through a Sip trunk to a sip device. When the call connects, the call does not pass dtmf to the connected device.
All the other phones in our network seem to pass dtmf over this trunk properly, except the new phone. I have updated the phone to version 1.1 of the firmware
I am also runnning CM 5.1.1
