Vonage's fax is useless. I've tried four or five different fax devices (several modems and two different fax machines), and not only was I unsuccessful, but I also got their support's "We don't support... XXX" reply every single time. When asked which device they DO support, the replies ceased. When asking for a refund on the activation fee and monthly fees for the fax-line, I was asked to contact tech-support to work out any problems.
