Hangs up when answering a call

[pmeat]

When trying to make an outgoing call using the demo provided on the site, the call completes but once it is answered it immediately hangs up. Noticed this error on the browser console:

app.js:226 Uncaught TypeError: Cannot read property 'displayName' of null
at Object.logCall (app.js:226)
at f. (app.js:126)
at f.d.emit (sip.min.js:35)
at f.b.receiveResponse [as receiveNonInviteResponse] (sip.min.js:35)
at Object.b.RequestSender.receiveResponse (sip.min.js:37)
at b.receiveResponse (sip.min.js:37)
at d.receiveResponse (sip.min.js:39)
at d.onMessage (sip.min.js:39)
at WebSocket.ws.onmessage (sip.min.js:39)

The callLog function receives a null value for the session param.

However, I don't think this is the reason for the hang up.
