About calling and phone numbers: these are charged based on how much you use them,
on top of your subscription, at the rates our carrier charges us. That is how every CRM
with a phone in it works — the difference is that the big ones ask $99–$139 per seat
before the calls. Here the software is $15 and the calling is near cost. There is a
note under
each feature setting out exactly what is metered and
what isn't, and calling from your own mobile is always free.
