As best we can tell, unless you have a VPM module on a TE4XXP board, it 
should _already_ be working this way for Zap<->Zap bridges. In that 
case, DTMF processing is completely bypassed, and it's left in the audio 
stream untouched.

Is your environment involving something other than Zap<->Zap bridges?
