Lots of people say faxing over VoIP just won't work, but at least for faxes with only a few pages and having a decent internet connection I've had excellent results.
I had a project using hylafax with about a dozen USB fax modems hooked up to a SIP gateway, connecting through a VPN back to the office where the PBX was and then out to our SIP trunk provider on G.711. It sent a lot of 2-10 page faxes. The system sent over a million faxes over its life, and excluding one receiver that tended to constantly have problems no matter what had an >95% success rate.
