[ale] Hylafax and Vonage

[Benjamin Scherrey]

    Your understanding about the connections is correct but fax signals, 
especially higher speed ones, are far less forgiving of timing issues 
than a person's natural voice recognition. So when there is any packet 
delay or stutter, that will make a fax lose sync real easy. Throwing 
more bandwidth (using the highest setting) and guaranteed response times 
(putting the vonage modem in front of other traffic) helps tremendously. 
The dependency is still in the analog audio signal that the fax hardware 
is using to transmit its information. Would be nice if someone had a 
VOIP fax that was out-of-band all the way until it got to the other 
end's connection. Closest thing I've seen is email!
