Hello, I have 4 polycom phones connected to an asterisknox based pc that make/receive calls though sip, all works great unless the internet is down. I have a BT telephone land line that I would like the 4 phones to be able to make calls through should the internet go down.
My question is would the Sangoma A200 plus one fxo/fxs module allow me to connect up the BT land line to the asterisk system and allow the 4 phones to route the land line???
