[comp.dcom.telecom] Building Your Own Home PBX

Is there anyone out there interested in working on designing a small
PBX for home use? I've been tossing the idea arount for some time now.
I know I can buy them, but there are advantages to building one's own:

- You can program it to do *anything*, and do it *exactly* as you want
it.  For example, in my local area there are only a dozen or so
prefixes.  I would like to choose extension numbers different from the
starting digits of these prefixes, and not have to dial an access code
for an outside line.

- If you have a good junk box, it may be cheaper.

- Building things is fun.

A group effort would help a lot in speeding up the process, and makes
the of producing PC boards more feasible, which would save a lot of
construction time.  I suppose electronic switching is best, although
at surplus prices Good Old Relays might be a viable option.  The thing
could be controlled by a single-board computer.

Anyone interested should write to me at gaarder@tcgould.tn.cornell.edu
on the Internet, or {backbone}!cornell!batcomputer!gaarder on UUCP.
