I am originating from esl, call is bridged with audio file. (Dialer setup). Some of the providers send dtmf  inband and others rfc2833. I am currently checking in my lua script for a custom param, if present then execute start_dtmf to listen for inband dtmf. While this breaks the rest of dtmf. Is there a better way to deal with this or do I have to end up with different profiles each with different dtmf-type.<br>
