I can assure you it is not the case.

Well, I'm not really enthousiastic to do it myself, because it is of no
use. It will only work from time to time, and not always.

I don't think it is a good solution, as there is no certitude it will
always work, even if you are called. Moreover, it is a hack for
misconfigured firewalls with Netmeeting behind. If you want to implement
it, then let's go, but I don't think it is very useful except in your
case where you will get 50% success.

You have to hack first in openh323 (look how the current IP translation
is implemented), then you will have to hack in GnomeMeeting itself. It
is much work for a bad solution.
