asterisk users - Dec 2003 - FWD via IAXtel?

Hello All,

It seems to me that passing SIP through my NAT router to * is a fair amount of
work what with patching * and opening router ports, etc. In my setup I only need
SIP to access FWD numbers.

I have found that any IAXtel user can dial FWD numbers using the prefix 170099.
Brief testing shows that this seems to work well for outbound calls to FWD. I
may also wich to route 800 toll free calls through IAXtel in order to keep my
few POTS lines free for incomming calls. However, I have heard that IAXtel in
not particularily reliable. Is this true? Does anyone here make significant use
of IAXtel?

Thanks,
Michael
