Hello everybody, I’m in trouble with freeswitch, there must be something i didn’t understood but i don’t know what. I want to add a user (no importance who it is (phone-number, name)) into a conference and this user job is to send sound into the conference (based on the http://lists.freeswitch.org/pipermail/freeswitch-users/2015-July/114783.html) Another part of his job is to keep the conference alive even if there is nobody inside So I did the following In the internal dialplan i put {{{ <extension name="playmedia"> <condition field="destination_number" expression="^ playmedia $"> <action application="endless_playback" data="/home/toto/medias/media.mp3" /> </condition> </extension> }}} And then I try in the conference to make a call to this dialplan from a conference {{{ conference 146806@[sip_profile_in_use] dial sofia/internal/playmedia }}} Normally the default user is used to make the call no ? The result of my command line is {{{ 2018-01-23 17:14:49.282641 [DEBUG] switch_ivr_originate.c:2142 Parsing global variables 2018-01-23 17:14:49.282641 [WARNING] mod_sofia.c:4664 Cannot locate registered user playmedia@internal 2018-01-23 17:14:49.282641 [NOTICE] mod_sofia.c:4918 Close Channel N/A [CS_NEW] 2018-01-23 17:14:49.282641 [DEBUG] switch_core_state_machine.c:741 () Running State Change CS_DESTROY (Cur 0 Tot 27) 2018-01-23 17:14:49.282641 [DEBUG] switch_core_state_machine.c:751 (N/A) State DESTROY 2018-01-23 17:14:49.282641 [DEBUG] mod_sofia.c:343 N/A SOFIA DESTROY 2018-01-23 17:14:49.282641 [DEBUG] switch_core_state_machine.c:751 (N/A) State DESTROY going to sleep 2018-01-23 17:14:49.282641 [NOTICE] switch_ivr_originate.c:2851 Cannot create outgoing channel of type [sofia] cause: [USER_NOT_REGISTERED] 2018-01-23 17:14:49.282641 [DEBUG] switch_ivr_originate.c:3848 Originate Resulted in Error Cause: 606 [USER_NOT_REGISTERED] }}} I don’t understand what happen.
