The vonage stuff uses the mac address "string" because it is guaranteed 
to be unique, and that string is available for scripts within (at least 
some of) the ata's to use.  Vonage does not have access to the mac 
address from a networking perspective, which is what you've already noted.

If you wanted to come up with some sort of mass-produced ata style box 
that could register itself with servers and use a unique password, what 
would you use? (Probably the mac address combined with an additional 
string.)

If you look at the sipura devices (and other devices with sipura 
software), you'll find the mac address is readily available and 
preloaded into a script variable for you to use.
