I've asked for more information to Equivalence, but that connection
doesn't have to be forwarded. However, it is weird that it has a random
local port.

Then give a phone call to the support service. I can't answer your
question. Either the router natively support H.323 and NAT, or it does
not. If it does, you don't need port forwarding and ip translation, as
described in the FAQ.

Then you really have a problem with the router configuration. Either
ports are not forwarded correctly, or it is messing the packets...

Not needed.

Yes, please do what I repeat you since a few mails... : check if the
router supports H.323 or not, then check that you can make normal calls,
not MicroTelco calls. Once you are sure normal calls work, and that your
configuration is correct, then you can start using MicroTelco.
