The NAT (Network Address Translation) section in the PBX system is used to ensure proper audio and signaling when your PBX is behind a router or firewall.
By specifying your external IP address and defining local network ranges, the system can correctly route SIP and RTP traffic between internal and external devices, avoiding one-way audio or connection issues.
Add NAT Setting
NAT Enabled: Activates NAT traversal support.
External IP: Set this to your static public IP. (If dynamic, use a DDNS service).
Local Network: Define internal network ranges.
ADD: you can add more than one local network.
- Note: For remote extensions, enable NAT in the extension settings as well.
