NOT true and I have proven that for the last year.

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.

If I had ANY failed faxes I would here about it. Iaxmodem creates a log of its own, so when I get a connection that fails hylafax sends the failure to me. One of the things that I found is you need to add nojitterbuffer to the iaxmodem config file, 
    

 
Really?  I'll have to do some testing, I've never tried since I've read 
you can't.
