We have a problem using a spa122 (or any cisco device) communicating with some IVRs over certain carriers. The carrier wants us to change the Marker Bits on the DTMF packets. Right now the first DTMF packet (for each keypres) has the marker bit set. They want to have the marker bit set on the first not-dtmf packet that is after the DTMF packets. They want to mimic the settings in a Polycom. Is there a setting that will allow the spa122 to do the set the marker bit?
