[Serusers] sipsak authentication problem

[Nils Ohlmeier]

Hi Klaus,

what you tried with a file is allready possible with the latested sipsak from 
CVS. It can use a given Contact for REGISTER.
But i have no real clue why you receive 401 twice. I'm pretty sure that the 
digest auth part of sipsak works fine. Can you try to run sipsak with -n to 
use IPs instead of hostnames in Via? Maybe this is related to the 
"NAT"-detection at iptel.

Greetings
  Nils
