[asterisk-users] Asterisk calls between 2 private networks

[Frank]

AJS,

That is a solution that I am envisaging.
But I would really love to try to work out with my issue first. It will 
allow me to deploy more phones in separates buildlings in the future. If 
I do the IAX solution, it means that for every building, I need a box.. 
Which I would like to prevent.
