[Serusers] X-Lite and SER (again) New info

Hello,

I'm sorry to come back again with this topic :( ... i've installed a new SER
from cvs (rel_0_8_11) and when trying to register X-Lite 2.0, X-Lite does not
send authentication information. As before, i can register an ATA186, a SNOM
100 phone and SIPPS but no X-Lite. I think the problem is in my X-Lite
configuration and that it's my fault but after looking up and down i can't
find the problem.

This is X-Lite configuration:

SIP Proxy
  Enabled: yes
  User Name: 1000
  Authorization user: 1000
  Password: 1000
  Domain/Realm: voztelecom.net
  SIP Proxy: 192.168.1.2:5060
  Out Bound Proxy:
  Proxy Mode: Normal
  Send Internal IP: Off


These are the X-Lite logs. The most strange thing is that it does not answer
the auth requests from SER (below is Cisco ATA REGISTER log and SER
configuration):
