Don't be too sure, Robert.  You can be fairly certain that alarm
manufacturers are working on this already.  The telecommunications universe
is evolving faster than many other fields.  Alarm manufacturers have two
choices: develope VoIP compatible communicators or become obsolete.

There are workarounds though they sound a bit less secure than a
conventional line.

I'll be experimenting with several systems over VoIP service shortly.  I'm
changing my company's phone system into a "virtual office" space.  We'll
have a single number to dial and an auto-attendant to distribute calls
between employees in three US states plus one office in Brazil.  The new
system will allow us to instantaneously transfer a caller between stations
anywhere in the world.

It appears that VoIP is not quite ready for prime time when it comes to
alarm system digital communicators.  However, I expect we'll be seeing
improvements in that area soon enough.  Meanwhile, if your VoIP service
includes a second port which is optimized for analog fax service you might
want to try sending alarm signals over that line.  I plan to test that
shortly using DSC, Elk and Napco panels I have on hand and will let you know
if it works.
