[Freeswitch-users] DTMF confusion

[Jesse Peterson]

Hello,

If I wanted a bridged call to a gateway to use inband DTMF for  
incoming recognition and outgoing generation I'm unclear on what to do  
because the wiki clearly states[1] not to use the "start_dtmf" and  
"start_dtmf_generate" together for cause of loops.

Wouldn't it be technically possible to generate DTMF only on the  
outbound leg and recognize DTMF only on the inbound leg without  
interference?

I assume I'm not understanding something correctly here - could  
somebody elaborate? The end goal for me is to detect the absense of  
"telephone-event" rtpmap and enable inband DTMF from a gateway.

Thanks!
- Jesse
