By default, the IP Phones will receive a list of Cisco CallManager hostnames they can use to register from the TFTP server. How can you modify this so the IP Phone receives a list of Cisco CallManager IP addresses from the TFTP server?

  1. You must manually edit the IP Phone configuration files on the TFTP server, replacing hostnames with IP addresses.

  2. You must access the Cisco CallManager server configuration from System > Server and change the hostnames to IP addresses. The Cisco CallManager will automatically update the TFTP server.

  3. The IP Phones must use hostname resolution to communicate with the Cisco CallManager. Ensure DNS redundancy is in place.

  4. In the Cisco CallManager, access the Service > Service Parameters window and change the preferred resolution method to IP addresses rather than hostnames.
