I know there are a few users without problems.

yes correct

Then that's a bug on their end as they are using H.245 Tunneling and
Fast Start (and you should be doing it too in your preferences).

Yes, 5010:5010 is invalid and thus ignored.

For your configuration, I would say 5010:5011 for the gatekeeper,
5000:5002 for audio RTP, and that's all with fast start and tunneling

Both should be enabled.

Not normal if H.245 Tunneling is enabled. Normal if it is disabled, but
MicroTelco requires it to be enabled. And the PC to Phone config window
should enable those settings for you automatically.
