Enable DNS SRV lookups on outbound calls Note: the
gateway only uses the first host in SRV records Disabling
DNS SRV lookups disables the ability to place SIP calls
based on domain names to some other SIP users on
the Internet specifying a port in a SIP peer definition or when
dialing outbound calls with suppress SRV lookups for that
peer or call.
Whether enable the internal SIP calls or not when you select
the registration option "Endpoint registers with this gateway".

Network Change
Event
Through the use of the test_stun_monitor module, the gateway
has the ability to detect when the perceived 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 only takes effect once
res_stun_monitor is configured. If res_stun_monitor is enabled
and you wish to not generate all outbound registrations on
a network change, use the option below to disable this feature.
