If you look at the default dial plan in FreeSWITCH you’ll see this:<br>
<br>
<condition field="${switch_r_sdp}" expression="a=rtpmap:(\d+)\stelephone-event/8000" break="never"><br>
<action application="set" data="rtp_payload_number=$1"/><br>
<anti-action application="start_dtmf"/><br>
</condition><br>
<br>
This will look at the SDP and toggle on start_dtmf if no telephony-event is present in the inbound invite.<br>
