Sorry for top posting my bb is dumb about that. The answer to your question is yes, you can uses your current pots lines. You want your outside line to be fxo and lines connecting to your standard phones to be fxs. The digium wildcard supports 4 pots and you can buy them with a different mix of fxo/fxs, they are simple removable modules. Don't waste your time with a x100p card, they suck and will be more of a waste of time then they are worth. Sent via BlackBerry from T-Mobile

This brought an idea in my mind... the phone lines in our houses here in Quebec,Canada are set so the line comes into the house at one point (called dmark i think) then it is spread around. if there is no service, then there is no dialtone, if one phone is used, then all phones can hear the conversation if picked up. normal stuff. but what if i were to setup a pc to work with asterisk and somehow plugged a FXS (i guess?) card to any phone jack in the house. then any normal phone would be networked to that FXS card and anything done on them will go through the PC (the pc will actually take care of sending a dialtone, etc...) am i correct, is this possible (to use the existing POTS infrastructure)? Thanks
