I'm planning to start a business that requires multiple incoming
lines, probably 50+ lines. Incoming call for each line will be routed
to a designated number. The requirement is that all calls must be
recorded & logged. -- I called local phone company and they said it's
about $20/month for each line. I believe there are solutions out there
that allow me to do this with more lines & cheaper rate, but I have no
idea where to start.

It would be great if I don't have to invest much in network equipment
and such. But if I have to, I'd love to know how much it's likely to
cost. I've seen many businesses can offer a phone number to customers
at a very reasonable price. (OneSuite Voicemail service $1/mo,
Copycall service a few bucks a month) I know there's a way to do this.
Please shed me some light.
