I suspect is something related to NAT traversal ....maybe the far-end 
NATs are differently "seen" than the ones from the local NAT....

Maybe if you make a trace of the signalling (ngrep) on the server, we

script ? :D

for siptrace (dir config/tools/system/siptrace ) - put the IP of your 
opensips in $proxy_list...
