The externip, externhost and localnet settings are used if you use IP PBX behind a NAT device to
communicate with services on the outside.

Extern IP
Address that we're going to put in outbound SIP messages if we're
behind a NAT.
Extern Host
Alternatively you can specify an external host, and IP PBX will perform
DNS queries periodically. Not recommended for production
environments! Use externip instead.
Extern Refresh
How often to refresh externhost if used. You may specify a local network
in the field below.
Local Network

localnet=192.168.0.0/255.255.0.0; All RFC 1918 addresses are local
