Hey Bill,
Although it sounds like a plan, if you add the extra costs of the additional line and the cost for services that are included in my
VoicePulse plan it's really not a bargain. Sure you could recover your cost in 18 months, but only if you don't have the additional line and services, which I think are essential.
Then there's the possibility that they can't survive the market forces and your stuck with an exclusive box that can't be used on any other IP network. I would need to give it some time before I jumped in.
