[Nice] component-state-changed change to FAIL

Hi,
The issue is that you're using the numb server.
From http://numb.viagenie.ca/ :
Numb conforms to the following specifications:
- RFC 3489
- draft-ietf-behave-rfc3489bis-15
- draft-ietf-behave-turn-07
- draft-ietf-behave-turn-ipv6-04
The problem is that turn draft 7 is very old.. libnice supports the RFC5766 TURN
specification (which was established in April 2010) while the
draft-ietf-behave-turn-07 draft was written in February 2008.
There were a total of 16 drafts before the RFC was established and the
differences between draft 7 and the RFC make them incompatible.
See http://tools.ietf.org/html/draft-ietf-behave-turn-07
I think it's time for Numb to update their server...
I suggest you use the software from turnserver.org which is compatible with the
RFC and is known to work with libnice.
(libnice did support numb a few years ago, but we had to keep updating the turn
support to the latest drafts).
If you just want to test it with Numb, you can patch libnice to make it work
with it. Simply open agent/agent.c and find the "agent_to_turn_compatibility"
function (around line 176) and replace STUN_USAGE_TURN_COMPATIBILITY_RFC5766
with STUN_USAGE_TURN_COMPATIBILITY_DRAFT9.
This should make libnice use the turn draft 9 compatibility mode (draft 9 was
compatible with draft 7 and is known to work with the Numb server) and it should
just work.
Note that this is obviously not something I'd like to expose as an API or
anything because it makes no sense to be working on older drafts now that the
RFC is finalized.
Hope this helps,
Youness.
