Maybe.. but, when I turn ON, I see fs_path-es for outer clients. If it 
is OFF, I never see fs_pathes.
Can you suggest, how to enforce "fs_path-es without 
aggressive-nat-detection"?

Also, I see another problem:
My friend in the Ukraine, uses phone behind NAT, too (situation like to 
Sipdroid - he also behind NAT).

There is his registration record:

Call-ID:        c4e76211 at 192.168.10.103
User:           1012 at 192.168.1.5
Contact:        "user" 
<sip:1012 at 192.168.1.136:1024;fs_nat=yes;fs_path=sip%3A1012%4091.207.244.1%3A1024>

When he calls me, everything is OK, we can talk each to other.
But, when I call him (from LAN), he receives RING signal, pick up 
handset -- and we both heard nothing.

Can you suggest, where to search?
