google的naitive c++ webrtc生成的sdp通过exosip发送给freeswitch后报错如下:
Reason: Q.850;cause=88;text=“INCOMPATIBLE_DESTINATION”
FS官方各种报错码解释:
https://developer.signalwire.com/freeswitch/FreeSWITCH-Explained/Troubleshooting-Debugging/Hangup-Cause-Code-Table_3964945/
488码的意思是兼容性问题:
This cause indicates that the equipment sending this cause has received a request to establish a call which has low layer compatibility, high layer compatibility or other compatibility attributes (e.g. data rate) which cannot be accommodated.
