[sr-dev] [kamailio/kamailio] kamailio re-INVITE (Issue #3840)

Is there a problem with my handling and how can I solve it? 1、Freeswitch INVITE to kamailio without video code 2、kamailio request to rtpengine(rtpengine_offer("record-call=off force trust-address replace-origin replace-session-connection UDP/TLS/RTP/SAVPF"))and call to jsSIP 3、jsSIP response with "SIP/2.0 200 OK" to kamailio without video code 4、kamailio request to(rtpengine_answer("record-call=off replace-origin replace-session-connection DTLS=passive ICE=remove RTP/SAVPF"))and response to Freeswitch 5、jsSIP send re-INVITE to kamailio with video code 6、kamailio request to(rtpengine_offer("record-call=off replace-origin replace-session-connection DTLS=passive ICE=remove SDES-off UDP/TLS/RTP/SAVPF"))and response to Freeswitch 7、Freeswitch response with "SIP/2.0 200 OK" to kamailio with video code 8、kamailio request to(rtpengine_answer("record-call=off replace-origin replace-session-connection rtcp-mux-accept rtcp-mux-offer DTLS=passive SDES-off UDP/TLS/RTP/SAVPF"))and response to jsSIP 9、Freeswitch send re-INVITE to kamailio with video code 10、kamailio request to(rtpengine_offer("record-call=off replace-origin replace-session-connection rtcp-mux-accept rtcp-mux-offer DTLS=passive SDES-off UDP/TLS/RTP/SAVPF"))and response to jsSIP 11、jsSIP response with "SIP/2.0 200 OK" to kamailio with video code 12、kamailio request to(rtpengine_answer("record-call=off replace-origin replace-session-connection rtcp-mux-accept rtcp-mux-offer DTLS=passive SDES-off UDP/TLS/RTP/SAVPF"))and response to Freeswitch -- Reply to this email directly or view it on GitHub: https://github.com/kamailio/kamailio/issues/3840 You are receiving this because you are subscribed to this thread.
