DNS and Hostname Resolution with Cisco Business Edition 3000 system
This document does not provide detailed information on DNS. You should have a thorough understanding of DNS before you use it with your Cisco Business Edition 3000 system. DNS is optional; you do not have to use a DNS server unless you plan to resolve hostnames for your Cisco Business Edition 3000 server or gateway. If you include a hostname for the server or gateway on the Network or Gateway page and you must use DNS, make sure that you map the hostname(s) to the IP address(es) on the DNS server for both forward and reverse DNS resolution. Cisco recommends that you perform this task before you add or edit the hostname in the Cisco Business Edition 3000 GUIs.
The current version of the Cisco Business Edition 3000 does not require a DNS server; however, it is configured for future requirements such as SIP trunks.
Note Cisco recommends that you do not configure Cisco Business Edition 3000 to use DNS.
