- Use static address (not absolutely required, but recommended for ease of management). Define IP Address, Netmask, and Gateway.
- DNS. Domain should be your SIPX domain, and set the Primary Server to your SIPX server (if you are serving DNS from the SIPX server) or to the appropriate server with the correct SRV records.
- NTP. IP or FQDN should be set to an appropriate NTP server. I recommend the SIPX server. Time Zone should be set as appropriate.
- UPnP. Enabled, and Broadcast announcements checked.
