Hi Daniel!

This reveals another question: What is the difference between: request 
URI, first branch, all branches, destionation sets .....

I used xlog to log all this pseude variables just before t_relay.

   first branch:    $br=sip:klaus at 10.10.0.50:8718
   all branches:    $bR=sip:klaus at 10.10.0.50:8718
   destination set: $ds=Contact: sip:klaus at 83.136.33.19:5060, 
sip:klaus at 10.10.0.50:8718
   destination uri: $du=<null>
   request uri:     $ru=sip:klaus at 83.136.33.19:5060

In the above call scenario, there is just lookup() which reveals 2 
contacts, one with public IP and one with NATed IP (received structure 
used).

Can you please describe the difference of these variables?

- Why does the destination set contains the NATed IP instead of the 
received-IP?
- Why does all branches only shows the first one?
- Why is the request URI different to the first branch?
