Summary:                    Snom phones occasionally fail to register in
1.6.1.3rc1
Description: 
Sometimes Snom phones fail to register and just display "NR":

user=776-000413245bda-1, realm=asterisk
[2]5/8/2009 14:00:05: Registered at registrar as
776-000413123456-1 at 10.0.1.5 (Expires: 60 secs)
[5]5/8/2009 14:00:05: sip::process_auth:Match challenge for
user=776-000413123456-1, realm=asterisk
[2]5/8/2009 14:00:05: Registrar 776-000413123456-1 at 10.0.1.5 refused with
code 401
[5]5/8/2009 14:00:05: Will try to reregister in 20 seconds

I have put a packet dump in "additional information". I have changed the
name to Phoneuser and the MAC address to 000413123456 for privacy reasons,
but everything else (including IP's) are unchanged.

Notice how Asterisk first responds "OK" and then "Unauthorized" in the
final two packets.

The problem does not occur with 1.6.1.1. I have not tried 1.6.1.2 yet.
