RHC: "It will work some or most of the time under some conditions" is
pretty much the definition NOW of how alarms work with all current
VoIP services. That's exactly why reputable companies wont touch VoIP
on alarms !!

 If this is any better, it may offer a solution of some sort; however,
I see your point and acknowledge the worth of it. The question really
is "how MUCH better is this VoIP than previous ones and at what point
is it reliable enough???

Gotta say, I don't know the answer to THAT question....
