Well, that’s a new one!
I’d be happy to document it in the wiki if someone can provide a useful description of what it controls.

Try setting channel variable "sensitive_dtmf" to true.

I'm coming across a strange, intermittent behavior with RFC2833 DTMF packets. This is occurring in a production environment, and I've been able to duplicate this with a very minimal FreeSWITCH installation in a virtual machine.
Details of the problem:
A customer occasionally has a problem report where their callers are unable to use the IVR menu. From the user's standpoint, the digits are not detected. Upon further review, we do receive DTMF event packets from the carrier, however, they do not traverse the bridge from the A leg to the B leg.
