When I use sipml5 call xlife. Both them run on my computer. They will be able to connect to each other.But couldn’t hear the sound of both parties.
When I caught found both sides only upload udp to asterisk.But asterisk has no return anything.

When I use xlife call sipml 5.The Javascript console :
DOMException: Failed to parse SessionDescription. a=fingerprint:SHA-256 Failed to create fingerprint from the digest.
DOMException: CreateAnswer can’t be called before SetRemoteDescription.
Uncaught TypeError: this.o_local_stream.stop is not a function
