Hi Nikolay,
I confirm the issue. You did an excellent deep analysis. I cannot tell
if there is a solution playing with the phone config.
I would suggest to try to set manually in your Identity (SIP) Server
Type Support to Nortel. I couldn't find a good reason to set it myself,
but someone reported it solved some issues.
The only option I see that might be related is:
Authentication for SIP Reboot
but from the help it doesn't seems the solution.
Let me know. If you find something interesting keep me updated. I might
add your discoveries to the Snom plug-in.
Thanks
Alberto

Hi all,
I found that when snom phone is rebooted it does not terminate current
registration.
To be more precise snom 360 (firmware 7.3.26) phone attempts to clear
old registration.
The phone sends Register with Expires=0.
But sipX (4.0.2-016420, installed from iso) challenges this
"unregister" message, while the phone continues to reboot without
sending the next "unregister" with Authorization header.
Thus I have "hanging" registration (until it expires).
And the same situation with snom subscriptions (with the exception
that hanging subscription dies after the next notify).
Has somebody encountered this problem?
What can be done with it?
Is there an "always send authorization header" configuration option
for snom? (I did not find it).
Do I understand right, that sipX will always challenge Register and
Subscribe messages?
Please help...
Thanks in advance,
Nikolay.
