A dart-lang version of the SIP UA stack, ported from JsSIP.

• Use pure dart-lang
• SIP over WebSocket (use real SIP in your flutter/web apps)
• Audio/video calls (flutter-webrtc) and instant messaging
• Support with standard SIP servers such as OpenSIPS, Kamailio, Asterisk and FreeSWITCH.

Thanks to the original authors of JsSIP for providing the JS version, which makes it possible to port the dart-lang.
