[asterisk-users] Mac Address Authentication Methods

[Daniel Botelho P. Moraes]

Hello all !

I am looking for a way to use an ata or ipphone mac address as a part of the
sip registration.
I've tried using arp tables, but it only works on local networks not thru
the internet..
I know that vonage uses some kind of mac auth, but I think that this is an
special feature of their equipments ain't it?
Have anyone accomplished this? 
Any ideas would be very very appreciated

Thanks
