She is behind a firewall or NAT gateway. She has to configure it so that
Netmeeting works behind it. Perhaps the XP personal firewall is enabled.

It should do it though.

Then everything is correct.

Yes if G.711 is allowed, but it requires high-bandwidth. Other codecs
are proprietary and patented. You can use them if you buy a quicknet
card.

That proves nothing.

It is apparently not your problem. Your problem is that she is
unreachable because of NAT or firewall rules...
