I am facing a issue while hold/resume a call using sipml5 phone.
while unholding a call I got below mentioned error on my asterisk cli. and customer end is unable to hear anything. please help me.
Please provide “sip set debug on” output contain at least the SDP exchanged in both directions for the initial INVITE, the re-INVITE to held, and the failing re-INVITE.
It seems as though the WebRTC client isn’t actually unholding, but is instead adding a second audio stream which is unsupported. The “sip set debug on” mentioned by David will confirm this.
