Afaik this capability has been around for a long time, but I've never used aix with nat.

Cor, you need line wrapping! thunderbird does it for me but on hitting 

You are assuming that he has access and control to the client site or 
that the client side is an office. I think he has remote roaming clients 
in mind.

The main thing is to eliminate natting so adding a vpn client should fix 
that. That is what I did for my asterisk <-> nat <-> nat <-> sip-client. 
asterisk <-> vpn <-> sip-client is far less troublesome.
