Summary:                    SIP crash on transfer
Description: 
When trying to transfer a call from an Aastra SIP phone (6755i) --
A<-->B(Aastra)<-->C -- nonetheless call failed, but then Asterisk no longer
manager any SIP function.

Main Asterisk process still works, "sip show users" still displays users,
but phone are no longer registered, hard/soft phone cannot perform any new
registeration, no call can be done.

Even if I try to send a REGISTER UDP message through netcat from Asterisk
machine, I don't see anything in a Asterisk console (with sip debug
enabled).

It seems that a major part a SIP handling is then broken. Moreover I can't
reload sip module from Asterisk console. I need to kill it before
restarting service.
