RTP Port Forwarding References

To correct the port forwarding. You might need to refer to your router user guide.

Well, we can show RTP port forwarding example here:

Firstly check the RTP port range on the PBX.

Then make port forwarding on the router. The port forwarding should be symmetric like:

  • PBX Internal Port Range: 10000-12000
  • PBX External Port Range: 10000-12000

For example, make port mapping on ROS Mikrotik.

Go the menu: IP> Firewall> NAT

Add NAT Rule for RTP ports.



On the other hand, you can refer to the setting for other brands.

(Note: It might not include the port mapping screenshots, but you can refer to the guide to make it.)
