After seeing the link Mark Loyd posted, I think I am going to buy one
of these at Best Buy tomorrow.
I was also thinking outloud how I might get this thing to work without
rewiring my phones.
I have a phone jack at my computer that used to be use for dialup. I
can plug the (modem?) (interface?) in the phone jack. I can then go
outside and unplug the phone at the phone company's box. This would
have all the phones the house wired to the interface.
Would it work? I will let you know tomorrow.
If this doesn't work, I can plug in my cordless that has an extra
extention and still have two phones in the house working until I can
get extra extentions.
I did find this link that says you do get an incoming number.
