I should have done some more work before posting...but I am looking at a neat door intercom system for my home. The DoorBell Fon with the brass outdoor station looks absolutely perfect....with one lone problem...I don't know if it will blow up my Linksys phone adapter used with my VOIP provider.
I am under the impression that the adapter would only be damaged by ringing voltage sent from a typical central office, and that the DoorBell Fon probably would be fine if I simply plugged in the phone adapter to the Doorbel Fon unit and the output to my homes premise wiring serving my phone handsets. But I am not sure if this my introduce excess voltage or current that will fry my VOIP adapter.
The only other alternative would be to set up some designated handsets for the DoorBell Fon, but that would be little dorky.
Any thoughts or technical links anybody can offer? Thanks.
