I recommend that you "try before you buy".  I suggest having a demo of
proposed equipment, preferably right around Noon or 1pm and/or 9am to
see how it sounds.

The quality of VOIP varies greatly, usually due to bandwidth and latency
of the network.  Most Internet Providers' Internet access is NOT
designed to support latency-sensitive applications such as VOIP.

Many such solutions have poor phone quality, typically "choppy" sound.
Such a solution for a company would loose customers.
