A call with a SIP endpoint over TCP results in a call disconnection when the TCP SIP connection closes.

What steps will reproduce the problem?
1. Setup a trunk/PBX that only does SIP over TCP
2. Start up a WebRTC call (I tested this with an inbound call to the browser)
3. Call will drop in roughly 40-50 seconds which is the result of what I assume 
is one of the sides closing up the SIP TCP connection from inactivity. If 
either side sends a message it needs to reopen the TCP connection.

My "PBX" that is connecting to webrtc2sip is actually a node.js process using 
https://github.com/kirm/sip.js to interact and proxy requests from outside SIP 
trunks. Not sure if this information is relevant.

If I don't specify transport=tcp in the URI when connecting to webrtc2sip 
(resulting in a UDP connection) the call remains stable. This is my current 
workaround for this issue.

What is the expected output? What do you see instead?

Call should not drop.

What version of the product are you using? On what operating system?

webrtc2sip@rev.114
doubango@rev.998

on Ubuntu 12.04 64bit.

NOTE: I am not using sipml5 for this call. I assume the behaviour will be the 
same, but my test environment runs with a custom tool connected to webrtc2sip 
via WebSockets.

Please provide server logs with DEBUG level equal to INFO
