Outbound CID:Only works if the call was placed out through VoIP trunks.
DialPlan:Defines which type of numbers the web extension can dial.
Transport:WS or WSS.
WS:WS (WebSocket) Protocol which is an independent TCP‐based protocol providing
full‐duplex communication channels over a single TCP connection. The WebSocket protocol
was standardized by the IETF as RFC 6455 in 2011, and the WebSocket API in Web IDL is
being standardized by the W3C.
WSS:WSS (WebSockets over SSL/TLS), like HTTPS, WSS is encrypted and we strongly
recommend the secure wss:// protocol over the insecure ws:// transport. A variety of
attacks against WebSockets are almost impossible if the transport is secured.
Step 2:
Upgrade Web extension patch
As you can see, web extensions use different protocols for signaling and media (WS/WSS) and
they are not ordinary SIP/IAX2 extension that can use IP phones or softphones to register so must
be treated differently.
