Also be careful who you get your VOIP numbers from we used an Asterisk
server here at work till PHB made us put a *crappy* Avaya system in. 
We have an 800 number from Nufone that I've been 6 months trying to
port to a different carrier, and Bellsouth would not take over our
Voicepulse number.  We had too many problems with QOS outside our
network and had choppy/dropped calls so bad on our VOIP lines, that we
went to POTS lines and a digium card.  Also do your research on FXO
boxes/cards if you go the POTS line way.  We put Asterisk in at my
church and we have issues with our digium card every once and a while,
and I've heard the sipura boxes overheat.  I know our sipura fxs box
has issues here at work.
