Hello everyone, I'm having trouble getting SIP to work on my Mikrotik.
I have an RB3011 with a public IPv4 address, and on my local network, I have my FusionPBX server at the local IP 192.168.15.56.

I completed the initial FusionPBX setup and now I want to make it accessible through my domin (demo.juk.re).
On the Mikrotik, I set up the following port forwarding rules:


add chain=dstnat protocol=tcp dst-port=5080 action=dst-nat to-addresses=192.168.15.56
add chain=dstnat protocol=udp dst-port=5080 action=dst-nat to-addresses=192.168.15.56
add chain=dstnat protocol=udp dst-port=16384-32768 action=dst-nat to-addresses=192.168.15.56

I can register the extension successfully, but I can’t make or receive calls — the call connects but there’s no audio and it drops shortly after.
 
You may need to explain to Freeswitch that it is behind NAT. Add these variables. Flush the cache and restart FreeSwitch. Adjust your SIP profile accordingly.
