   ... even then, if you're running it over the Internet or even a slightly 
jittery WAN, it won't always work.  I have a 5300 and it's been tried.
Works pretty well over private IP transport, but fails about 25-50% of the
time when run over any substantial segment of the public Internet.

   Also, at least one thing I've run into / heard suggests that the AS5300s
are much better than the 5400s at handling low-speed analog and preserving
data integrity.  I know a CLEC that had to use 5300s in front of their
fax-to-email server to get it to work properly, with the results from the
5400s they otherwise use for MGWs being very mixed.

   Your mileage may vary on that one, though.
