NAT again?!

Hello,
I’ve got strange issue. I presume it has something with NAT, but I can’t solve it and honestly I don’t know where to start. I already read few posts about similar problems but they didn’t solve my problem.
Well, in internal network my calls work well. But I have a few extensions outside the NAT. When I call them, everything is ok. But when the other (outside) party calls me, he can’t hear me - and I can hear him.
Everything depends on who starts the call.
The router ports are opened and forwarded, I believe that my PJSIP settings, external and internal addresses are also correct (they are autodiscovered).

And I’ve got another question, but it may be connected with the first one. Sometimes I use MizuDroid client on my cellphone. I’ve got set my public IP address as SIP ip. So when I connect from external network, everything is ok, but when I call from local network, no sound can be heard. On the other hand if I changed the address to internal one, this work the opposite way (what is quite uderstandable). What to do to make possible internal and external calls?

At the Asterisk CLI,

rtp set debug on

It will likely show what asterisk sees as far as media streams are concerned, and help you identify what part of your network is misbehaving (and under what conditions…)

do that, make a failing call and post a snippet from the log.

For the one-way audio issue, confirm that the remote extension has:
RTP Symmetric, Rewrite Contact and Force rport all set to Yes, and Direct Media set to No.

For the second issue, set up a DNS name that points to your public IP address, but also set up a local DNS that resolves to the PBX LAN address. If your router/firewall acts as DNS server for your LAN, you may be able to configure a manual DNS entry to do this. Alternatively, set up the router so it handles ‘hairpinning’ properly (though many routers lack this capability).

If you still have trouble, paste a SIP trace (pjsip set logger on) in addition to the rtp debug.

The solution of second issue simple and elegant. Hats off and thank you.
The settings of external extension are correct. I will try to reproduce the call and paste the log.

Port 17040/UDP doesn’t appear to be being forwarded to you inbound.

It’s not opened indeed. But what it does?
Edit:
It’s opened, as it’s in the range 10000-20000
Do you suggest that NAT does not pass rtp?

The inbound RTP is not reaching Asterisk.

Ok, but how this can be, if all ports are forwarded from router and When I call the external party from internal network everything is ok.
Why the port does not open when the call is from outside?
Moreover, when I call from other external party (from mobile phone), everything works Well.
The problematic extension is zyxel sip gateway that is also a dls router. Should I open the ports on this device since the gateway and router are integrated in one device?
