I have three doubts that require some clear explanation .

  1. A clear purpose of those two JavaScript SIP library in relation to Webrtc and sip signalling.

  2. Difference between Sip.js and JsSIP JavaScript SIP Library.

  3. Does IP PBX means sip server or sip proxy as well

  1. Those are WEBRTC SIP libraries, the purpose is to add voice and video communication to a web app.
  2. No major difference. both have more less the same features.
  3. IP PBX means a business phone system, and a SIP server is the software that send the call to the phone device.

I also came across those both libraries today. I figured out, that you can't use them with your General SIP-Provider, if the Provider didn't support Sip over Websocket.

But you can use it with your SIP-Server / PBX (like Asterisk or FreeSWITCH), or with an Sip-Proxy like http://oversip.net/ (you also can have a look at the Outbound-Info for more Information: http://oversip.net/documentation/misc/outbound/
