As I am slowly piecing my home control system together,
one of the "later someday" ideas is to add a similar type
of switch to my residential line.. While this method is not
directly applicable to your situation, some may find these
(as yet just dreamware) ideas interesting.

I have seen Caller ID units that include a standard serial
port for ASCII output. Since I'll be wiring my own
house up for all the goodies, I'll tie all the phone lines
together in a star configuration. Later when this part
of the project is done, I'll be able to add relays to
selectively ring only particular phones based on the
caller ID number.

I am hoping to get my system to not only know what
rooms are occupied, but WHO is in each room. That
way, if a caller is recognized as the friend of a particular
family member, only the phone in the room that they are
in will ring. Of course, unrecognized callers or callers
recognized as other family members (in-laws) will
ring house wide.

Anyone on this list that does not see the value of this
feature has probably never had a 14 year old daughter.

I'll get there, I just have other parts of the project
to finish first.
