This demo shows how you can make use of the SIP plugin to interact with a SIP Proxy (e.g., Kamailio or OpenSIPS) or PBX (e.g., Asterisk or FreeSwitch) in order to place or receive calls to and from other SIP clients. Specifically, it uses the Sofia-based SIP plugin. Notice the plugin only exchange SIP messages from within the plugin itself: no SIP is done in JavaScript, except for references to SIP URIs.
When started, the demo will allow you to insert a minimum set of information required to REGISTER the web page as a SIP client at a SIP Proxy or PBX you specify. This will allow you to call SIP URIs, or receive calls through the SIP Server itself. During a call, you'll also be able to interact with the PBX via DTMF tones, e.g., to drive an Interactive Voice Response (IVR) menu that you're being presented with.
