Match External
Address Locally
Only substitute the exeternaddr or externhost setting if it matches.
Dynamic Exclude
Static
Disallow all dynamic hosts from registering as any IP address used for
staticly defined hosts. This helps avoid the configuration error of
allowing your users to register at the same address as a SIP provide.
Externally Mapped
TCP Port
The externally mapped TCP port, when the gateway is behind a static
NAT or PAI.
External Address
The external address (and optional TCP port) of the NAT. External
address=hostname [:port] specifies a static address[:port] to be used in
SIP and SDP messages. Examples: External address=12.34.56.78
External address=12.34.56.78.9900.
External Hostname
The external hostname (and optional TCP port) of the NAT.
External Hostname=hostname[:port] is similar to
“External address”. Examples:
External Hostname=foo.dyndns.net
Hostname Refresh
Interval
How often to perform a hostname lookup. This can be useful when your
NAT device lets you choose the port mapping, but the IP address is
dynamic. Beware you might suffer from service disruption when the
name server resolution fails.
