2015-01-16: JsSIP 0.6.1 released

This new version includes Session Timers support.

If JsSIP becomes the “session refresher” it sends in-dialog UPDATE requests (without SDP body) at the negotiated interval. In case the remote peer becomes the “session refresher” JsSIP allows both incoming UPDATE (with or without SDP body) or re-INVITE.

A new UA configuration parameter session_timers lets the user disable Session Timers support by setting it to false.

A new field sessionTimersExpires in the options object of both UA.call() and RTCSession.answer() determines the default refresh interval (default value is 90, do not set a lower value).
