Port forwarding / Port mapping not working

Sun Jul 24, 2022 4:19 pm

Hi guys.

For some reason, I can't get my IP PBX on premises phone server to work with Mikrotik.

I have internal calls working, from extension to extension within my internal LAN.

However, when I ring the DID attached to the business, it goes to the phone carrier, and I have programmed in our public IP, with port 5060.

I have then mapped this port to the IP of the phone system in our LAN.

The phone rings, and I am able to answer it on one of the extensions. However no voice can be heard? I cannot hear the other person, and they cannot hear me.

Do you know why this is?

I have port forwarding set up for port 5060, and also port forwarding for ports 5000-25000 for RTP.

Anyone know what could be wrong?

Thank you.
