- Register for a Catapult (Bandwidth Application Platform) account here
- Register a SIP domain
- Create an endpoint/user
- If you want to make calls to the PSTN (normal phones) you will need a server to handler events from Catapult

if (!JsSIP.rtcninja.hasWebRTC()) {
alert("WebRTC is not supported. Please use another browser.");

You can hangup call with
session.terminate()
