If you are moving to analog phones it works the same way. If your
using SIP phones it is all over IP so you just plug the RJ45 into the
phone, into the wall, which runs to your switch and your PBX plugs
into the switch. Easy as pie :)
I too recommend separating your data and voice network. With your size
just grab a 24 port PoE switch for the voice network and another (non
PoE) for data. A high quality network will have a fat packet stream
(number not size) of no more then 35ms. and about 125kbs per channel
so if you are wiring your own office and have a t1 hand off (PRI /W
discreet channels not media switched) then you will be golden, but
that is way over kill for 15 people. So you may want to do 5 or so
POTS lines.
