Hi Anrzej,

Right question is 50% of solution. Unfortunately the question is wrong.
Almost nothing is clear.

You can register your phones (clients) and you even can start or receive
calls but there is an issue with audio/video? Is it correct?

In this case this problem is not related to kamailio. It is related to
pbx/media server that is possibly behind kamailio. But maybe there is no
any pbx behind?

Without additional configuration audio/video traffic will go end-to-end
which is a problem with external clients with no public IP.

And yes, you are right about 5060/udp. But everything depends on your
configuration which is not clear. Maybe you need additionaly 5060/tcp,
5061/tcp (TLS).

But ports range for media traffic depends on media server/pbx/rtp proxy
configuration and nobody can answer this question but you.

I hope this tips will help you a little bit.
