DTMF problems


#1

Having problems with DTMF being recognized by the IVR on analog FXO lines. If I call in from a local number or my cell, the IVR works fine. If the call comes in from out-of-state, the DTMF is not recognized.
The service provider is Bright House Networks in Florida.
Thanks for any help

Confirm what DTMF method the UCM is accepting. By default, it should use RFC2833. Try changing this to Auto for more flexibility. This is under SIP Settings–>ToS.

Thanks for the reply. I managed to track the problem to the service provider.
