I tried in the SIP profile: <param name="dtmf-type" value="none"/> And in dialplan default.xml / <extension name I put <action application="set" data="dtmf_type=none"/> and also I tried <action application="bridge" data="{dtmf_type=none} … None of those worked.

FS receives INVITE and at certain stage sends 200 OK with a SDP section, which always contains : a=rtpmap:101 telephone-event/8000 (what means ‘DTMF in RTP metadata’). Indeed the DTMFs come via RTP. I tried various FS configuration options to remove that line, without success. How to do it? How to tell a gateway to send DTMFs inband ? In advance thank you very, very much, Adrian. _________________________________________________________________________ The FreeSWITCH project is sponsored by SignalWire https://signalwire.com Enhance your FreeSWITCH install with disruptive priced SMS and PSTN services.
