t_lookup_request:too few headers was [Re: [Serusers] SIP notify via sipsak, too many hops loop]

[Nils Ohlmeier]

Read RFC3261 for branch values in Via or search this mailing for answers on 
this.
sipsak just sends what you gave to it. It does not try to fix broken messages. 
If you want to send broken messages, e.g. for testing purpose, you are free 
to do so.

BTW: there is a From header in your NOTIFIY, but it misses the "tag" 
parameter!!!

  NO
