Assigning DNS Servers
The DNS setting on the Cisco IP Phone allows users to specify remote computers
by host names, which are character strings with some mnemonic value, rather than
by using IP addresses, which are simply strings of numbers.
The phones use DNS to resolve the host name of TFTP servers,
Cisco CallManager systems, and web server host names when the system is
configured to use names rather than IP addresses.
