Hi, I want to detect call progress tone with start_tone_detect, but I can't get the event fired. My dialplan is: <extension name="skynet51"> <condition field="destination_number" expression="^(\d+)$"> <action application="start_tone_detect" data="1"/> <action application="bridge" data="sofia/gateway/skynet51/$1"/> </condition> </extension> The call senario is: Caller A is a user registered on local FS. Callee B is a user on remote gateway. A-------INVITE------------>B A<------100 Trying---------B A<-----183 with SDP-------B A<------RTP of Ring Tone--B The early media of ring tone or busy tone is transferred from B to A after 183. But I can't see the DETECTED_TONE is fired. I have set loglevel to 3 in spandsp.conf.xml: <descriptors debug-level="3"> I can only find some Tone segment at a frequencey less than 10: freeswitch.log.2013-04-02-02-03-38.1:2013-04-01 21:51:12.618263 [DEBUG] mod_spandsp_dsp.c:645 Tone segment: f1 = 4, f2 = 5, duration = 48 freeswitch.log.2013-04-02-02-03-38.1:2013-04-01 21:51:12.738255 [DEBUG] mod_spandsp_dsp.c:645 Tone segment: f1 = -1, f2 = -1, duration = 128 freeswitch.log.2013-04-02-02-03-38.1:2013-04-01 21:51:12.858249 [DEBUG] mod_spandsp_dsp.c:645 Tone segment: f1 = 4, f2 = 5, duration = 112 freeswitch.log.2013-04-02-02-03-38.1:2013-04-01 21:51:12.958243 [DEBUG] mod_spandsp_dsp.c:645 Tone segment: f1 = -1, f2 = -1, duration = 112 freeswitch.log.2013-04-02-02-03-38.1:2013-04-01 21:51:13.018238 [DEBUG] mod_spandsp_dsp.c:645 Tone segment: f1 = 4, f2 = 5, duration = 48 freeswitch.log.2013-04-02-02-03-38.1:2013-04-01 21:51:13.058236 [DEBUG] mod_spandsp_dsp.c:645 Tone segment: f1 = -1, f2 = -1, duration = 48 Is my dialplan incorrect? I will very appreciate your suggestion. Thanks! Regards, Henry -- View this message in context: http://freeswitch-users.2379917.n2.nabble.com/start-tone-detect-but-no-event...
