Please I am new to freePBX I have a FreebPBX box with several extensions. One extension is local (same network as PBX), and two way audio works completely fine through the trunk. Several extensions are remote and they either have one way audio, or no audio at all.
I am running FreePBX 15, all extensions are setup as chansip, is on port 5060, 10000:20000) all of which are port forwarded through my firewall to FreePBX. . The local network is set to use 192.168.1.0/24.
