Domain (DOMAIN)
The SIP domain that specifies domain-specific NAT/FW traversal values.
STUN server address (STUNSRVADDR)
This parameter defines the STUN server address in the domain-specific NAT-FW settings. By default, the DNS SRV query tries to find the STUN server.
Use the value 0.0.0.0 to disable the STUN server, for example if an SBC is taking care of the NAT traversal.
STUN server port (STUNSRVPORT)
This parameter defines the STUN server port in the domain-specific NAT-FW settings.
Default value: 3478.
NAT refresh TCP (NATREFRESHTCP)
This parameter defines the NAT refresh interval for TCP in the domain-specific NAT-FW settings. The unit of the refresh interval is seconds. If an IAP-specific value for this interval is defined, it overrides this value.
Minimum value: 30.
Default value: 1200.
NAT refresh UDP (NATREFRESHUDP)
This parameter defines the NAT refresh interval for UDP in the domain-specific NAT-FW settings. The unit of the refresh interval is seconds. If an IAP-specific value for this interval is defined, it overrides this value.
Minimum value: 15.
Default value: 28.
