Hi guys! Im having some problems while trying to connect to a Freswitch PBX using OverSip and JsSIP. Using Jssip i can recive calls but when calling from the OverSIP/JsSIp I always get a 422 error. Softphone -> WebRTC ext calls OK WebRTC -> Softphone fails WebRTC -> ECHO TEST call on freeswitch also fails Can somebody help find out what this could be?
