JsSIP processing re-INVITE #852

Closed happytulubi closed 5 months ago

happytulubi commented 5 months ago

Now there is a call scenario where freeswitch ->webrtc (jsSIP) voice is normal and the video cannot be displayed. May I ask if jsSIP receives re INVITE and how to process the video

1、Freeswitch initiates a call to jsSIP without carrying video encoding 1、jsSIP receives INVITE with in SDP 2、jsSIP answers with "SIP/2.0 100 Trying" 3、jsSIP answers with "SIP/2.0 180 Ringing" 4、user picks up a call, jsSIP answers with "SIP/2.0 200 OK" 5、Freeswitch answers with "ACK SIP/2.0" 6、Freeswitch sends re-INVITE to jsSIP and carries video encoding 7、jsSIP answers with "SIP/2.0 100 Trying" 8、jsSIP answers with "SIP/2.0 200 OK"
