Will the service fit my needs?

Basically trying to see if VOIPo can fit with my situation
as I run a small home office, trying to cut my costs here
and there.

Usage-wise looking at about fifteen max calls
a day, but normal usage is more like zero to two.

Currently I have 2 residential lines with unique numbers
via Insight Communications (cable). It'd be key to get these
transferred since it's on our letterhead.

One line is kept separate for FAX use, although we use it for voice
once in a great while, we could probably live without the voice
functionality if need be.

Additionally we have a grandfathered 800 number through ATT that
simply redirects to whatever number we choose. Unless it would be possible
to keep the same number at a lower cost (switch everything to VOIPo), we'd
prefer to just leave this alone as is.

Lastly, we have a older Panasonic POTS base station with an integrated
pager call after a message is left on it's voicemail. Ten to one there's no way
of know if it'd work for sure, but I bring it up just in case there's some rare
known issue with similar phones.

Broadband line is 10MB down/1.5MB up with 42ms ping to VOIPo's website
and other addresses that I've seen while skimming the forums. We're running
about $67/mo. for the 2 lines and 800 number now.

Thanks.
