[Asterisk-Users] remote location.

[Satchid]

Dear members,

I have 2 locations with broadband internet. There will be an * on one
location and Wifi stations on both locations. The locations are to far away
to have the Wifi covering the distance. I want to use about 12 2000W
Portables phones on both places. The Wifi stations will not carry data for
computers, only VOIP.

How would I proceed to be able to use the Portable phones on both locations?
What hardware and/or what software do I need? Do I have to use VPN?
