[asterisk-users] SIP client MAC address.

This is a very strange discussion.

MAC addresses can only be discovered for peers that are on the same 
broadcast segment - which is the realm within which ARP lookups 
participate.

Any peers not on the same logical Layer 2 network are reached through 
a Layer 3 hop.  MAC addresses behind that routing hop cannot be found 
out because the nodes are in a different MAC domain.

NAT has absolutely nothing to do with this, and thus is irrelevant one 
way or another.
