Just for others looking later, here is the final code I came up with, with rtp_payload extracted. if session:getVariable("switch_r_sdp") ~= nil then local s = '[[' .. session:getVariable("switch_r_sdp") ..']]' if string.find(s, "a=rtpmap:(%d+)%stelephone%-event%/8000") ~= nil then freeswitch.consoleLog("debug", "NO NEED TO START starting spandsp_start_dtmf\n") local payload = string.match(s,"a=rtpmap:(%d+)%stelephone%-event%/8000") if payload ~= nil then freeswitch.consoleLog("debug", "rtp_payload_number = " .. payload .."\n") end else freeswitch.consoleLog("info", "starting spandsp_start_dtmf\n") session:execute("spandsp_start_dtmf") session:sleep(2000) end end Cheers Phil
