Is there a channel variable to disable/ignore 2833 DTMF messages that are going from the internal network toward the PRI?  I have a scenario where I am getting both inband and out-of-band DTMF (i.e. double DTMF digits).

 

This happens when a call comes in through the PRI and routes back out the PRI.  Inband DTMF coming from the caller is converted to out-of-band 2833 internally, so when the audio is routed back out the PRI, it contains both the inband DTMF and the 2833 conversion.  In some cases, we don’t want to use disable_dtmf, since we may need to detect inband DTMF in FreeSwitch.

 

Thanks,
