Heh. Yeah, that could've been clearer. I was referring to a Vonage voice
line, and not a POTS line. On POTS, this would be a non-issue. On Vonage,
because of the latency of the internet, normal "voice" codecs will make fax
calls unusable. The "fax" lines Vonage sells are better suited to fax
transmission by adjusting settings that aren't needing for voice, like max
bandwidth usage, changing packetization rates, and enabling high quality
codecs that won't mangle fax tones as badly. Although, if you have a Cisco
ATA, putting *99 before the number will force it to switch to the more fax
friendly settings before placing the call. *shrug*

I avoid the whole issue by not attempting to fax anything over my Vonge line. :)
