Actually, the very same thing used to happen to me with my ADSL modem.

When I first got my ADSL connection, the modem would lock up every time
I tried to make a H.323 call. No matter what I did, no matter what the
NAT and firewall settings, I simply could not make a H.323 call through
that modem.

After much investigation, I determined that the modem was trying to be
too smart. It was trying to proxy the H.323 connection for me, and it
the code in the modem was obviously buggy, so every H.323 call would
crash the modem.

I eventually solved the problem by disabling the H.323 proxy mode in the
modem using an undocumented command from the vendor. Since then, I've
not had a problem.

Maybe Gustavo is having the same like of problem. For the record, my
modem is a Dynalink RTA100
