A friend just turn me on to Broadvoice.
For less than $22 a month you get
UNLIMITED local and long distance (21 countries no less) calling through your broadband ISP.

That hardware is around $40 which is half the price if you bought it separately,
BUT, the 'adapter is locked out on the 1st phone port. You can't change any of the settings (voice quality for example). The 2nd port can be left unlocked if you request it.
