Hi everyone, I am trying to get FS to route inbound calls to an outside sip provider but I am getting the call hung up on the FS side just upon the first or second ring on the B-leg. The diaplan action being executed is: <action application="bridge" data="sofia/internal/ XXX@sip.linphone.org"/> I have a softphone registered to this provider sip.linphone.org and it works well when calling XXX from some other IP phone. FS reports this in the logs: [DEBUG] switch_ivr_originate.c:1274 Raw Codec Activation Success L16@48000hz 1 channel 20ms [DEBUG] switch_core_codec.c:221 sofia/internal/ anonymous@webrtc.sip.mydomain.co Push codec L16:100 [DEBUG] switch_ivr_originate.c:1343 Play Ringback Tone [%(2000,4000,440,480)] [DEBUG] sofia.c:6760 Channel sofia/internal/anonymous@webrtc.sip.mydomain.co entering state [terminated][500] [NOTICE] sofia.c:7779 Hangup sofia/internal/anonymous@webrtc.sip.mydomain.co [CS_EXECUTE] [NORMAL_TEMPORARY_FAILURE] [DEBUG] switch_core_codec.c:246 sofia/internal/ anonymous@webrtc.sip.mydomain.co Restore previous codec opus:116. [NOTICE] switch_ivr_originate.c:3523 Hangup sofia/external/ XXX@sip.linphone.org [CS_CONSUME_MEDIA] [ORIGINATOR_CANCEL] Result is the same if I try to call any other sip destination. I appreciate any input anyone may give: have been working on this for a week already. Thanks, Cato
