I highly suspect you receive phone calls from providers that don’t support RFC2833, fun thing is some providers do send 2833 but never say telephony-event in the SDP on the invite… which is silly.  If you look at the default dial plan in FreeSWITCH you’ll see this:

      <condition field="${switch_r_sdp}" expression="a=rtpmap:(\d+)\stelephone-event/8000" break="never">
        <action application="set" data="rtp_payload_number=$1"/>
        <anti-action application="start_dtmf"/>
      </condition>

This will look at the SDP and toggle on start_dtmf if no telephony-event is present in the inbound invite.
