Exactly, because the detector can get false positives too. Upstream sometimes will not squelch the entire DTMF out and some may slip thru and still get picked up by the inband detector. -- Brian West brian@freeswitch.org FreeSWITCH Solutions, LLC PO BOX 2531 Brookfield, WI 53008-2531 Twitter: @FreeSWITCH , @briankwest http://www.freeswitchbook.com http://www.freeswitchcookbook.com T: +1.918.420.9001 | F: +1.918.420.9002 | M: +1.918.424.WEST iNUM: +883 5100 1420 9001 ISN: 410*543 Skype:briankwest PGP Key: http://www.bkw.org/key.txt (AB93356707C76CED) On Mar 6, 2014, at 7:00 AM, Guillermo Ruiz Camauer <grcamauer@gmail.com> wrote:
If you are using RFC-2833, you do not need to "start_dtmf". I believe that is only used when you are receiving DTMF inband. If your provider sends RFC-2833, just disable inband DTMF.
