I've read faxing over VOIP can be tricky, at best. I assume Windows Fax is not in Vista x64 home prem version. So looking for simple one that will run under 64 bit, even in emulation mode. Also, a decent fax modem that'll work in Vista (new system didn't have one). DOUBT my old Creative one will work, but haven't tried, cause no fax prgm. In XP, the Windows Fax was fine for me using POTS. Now I only have DSL / VOIP. If anyone faxes over VOIP & wants to share some tips, I'd appreciate it. My provider (Future-Nine) has some suggestions for telephone adapter settings - that's about it. Thanks.
