We use a modem bank connecting our IP network and an external T1 to do just that. Depending on how many locations you're talking about that might be overkill.
I think what you're looking for would be some form of SIP proxy (for lack of a more intelligent term). Every IP (Internet) to phone service I've seen requires you to connect to their server (Yahoo Voice, Nortel, etc..). I don't think there are many (if any) "generic" SIP servers that allow connections from anyone or anywhere. No one would pay for VOIP services.
I could be wrong; probably am, but that's my 2c worth.

I tried Vonage with a modem, thier support could never get it to work and then wanted me to pay extra for a seperate modem line?
I switched to a new Voip Service PhonePower I have never had a problem with using a modem now for over two years.
Check out some of thier deals here:

Might try *99 with Vonage. This is their setting for faxes. I have used it dialing off the laptop to remote N30's. Works fine once the code is entered at the beginning o the phone number.
