DoorBell Fon and VOIP linksys adapters - can they co-exist?

["cribis" <chrisylvania@xxxxxxxxxxx>]

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.
