Can I use a fax machine with a VoIP system?

Will a fax machine work ok with a SIP/VoIP telephone system?

It's probably best not to bother with it, unless you absolutely have to have a fax.

Maybe, but I've seen very mixed results. Often they work poorly, if at all. It's really one of the few drawbacks of a VoIP system (or at least the limited number I've used). There may be ways to optimize fax over VoIP that I'm unaware of, but I would either maintain a single POTS line for fax, or go with an e-fax option.
