Excellent product once configured

This is the second time I buy this product, having lost by moving. And the second time I set up the galley with VoipCheap because this operator is not in the database configuration list. In this case, the manual is useless and does not find much help on the internet.
Once we checked the appropriate box Configurator (no chance) however, this works very well and is very nice. He can juggle incoming and outgoing local fixed line Internet calls without having to think about it.
The program is powerful and goes 2 floors of concrete.
The configuration will keep even changing countries and internet provider.
