external network address has changed. When the
stun_monitor is installed and configured, chan_sip will
renew all outbound registrations when the monitor
detects any sort of network change has occurred. By
default this option is enabled, but res_stun_monitor only
takes effect once. If res_stun_monitor is enabled and you
don't want changes on the network to cause an outbound
registration, use the option below to disable this feature.
Match
External
Address Locally
Only substitute the extern address or extern host setting if
it matches.
Dynamic
Exclude
Static
Dynamic hosts are not allowed to register with the static
host's IP address, which will avoid the same IP registration
error.
Externally
Mapped
TCP Port
The externally mapped TCP port, when the gateway is
behind a static NAT or PAT.
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.
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.
