One way audio issue

FreePBX Configuration

1

Hi,
I am having problems with one way audio on my freepbx. So there is a outgoing audio but not incoming on calls.

There is one sip trunk. I am using sophtpones on local network 192.168.100.0/24. Also one interface on freepbx is in that network. Sip interface is on 10.79.104.0/22.
There is a router with external address 217.71.54.244.

So ive tryed several things, forwarding rtp ports, changing nat settings , etc.
After sending logs i recieved info that registration of the sip is coming from 10.xxxx intreface but media is coming from external address 217.71.54.244.
So there is a routing problem but i have no idea what to do.
Also i got info that media for calls is coming from

10.252.67.201 and 202 ip from provider

Does anyone have some tips.
Thanks

Disable the SIP ALG feature on the router, and make sure you have correct external addresses and local networks on FreePBX.

Sounds like you’ve not enumerated all local networks/subnets in Settings → Asterisk SIP Settings. Changes on this page may require an Asterisk restart. [ edit - missed david55’s reply before replying]
