I'd say "consider yourself very lucky". I know I did some testing here
some time ago with faxing over VoIP.
* One extension to another over G711a with both extensions on the
same LAN - worked 95% of the time
* One extension on my Asterisk server to an Extension on a friend's
Asterisk server using G711a via IAX - 95% failure rate. Both of
us awere on the same ISP and had ping times of ~40ms between us.
However, in a live environment, I convert a PSTN call to a t.38 encoded
call and can send the fax just about anywhere I damn well want (where
the remote end supports t.38) with a 95% success rate.
t.38 is the key to successful faxing over a VoIP network. Without it,
you're begging for trouble.
