It is to fit a single customer need.
The customer is a militar and even if it is not compulsory,
if the solution would be militar-grade it would be a plus.
Unfortunately, having voice over a vpn would not be an option,
because 3G hsdpa is not available anywhere.
I think that I'll do some research about hardware, dedicated solutions.
Thank you again and have a nice day,
Mike
