B, C, C, E, and F
Although a device pool can assign other settings, Cisco CallManager absolutely requires these elements to create a device pool.
A Cisco IP Phone 7960 only has a total of six line/speed dial buttons available, which immediately eliminates answers C and D. The IP Phone must have at least one line button assigned to it, which eliminates answer A. Answer B represents the default phone button template assigned to the Cisco IP Phone 7960.
To configure auto-registration, you must access the System > Cisco CallManager configuration screen and access the server for which you want to perform the auto-registration. Once there, you can define the range of extensions that the Cisco CallManager should assign to the Cisco IP Phones.
The Cisco CallManager ties configuration information to IP Phones through the MAC address. This is one of the most difficult aspects of adding Cisco IP Phones to the SQL database.
The Region configuration allows you to define the codec used to communicate within the IP Phone's region (typically a LAN environment) and with other regions (typically communicating over the WAN).
By changing the hostnames to IP addresses under the System > Server menu, the Cisco CallManager will automatically update the TFTP server configuration files to use IP addresses rather than hostnames. This eliminates an IP Phone's reliance on DNS.
The Cisco IP Phone uses a list of up to three redundant Cisco CallManagers for registration. This is known as its CallManager Group.
You cannot modify or delete the default CMLocal date/time group. IP Phones using this date/time group will use the same time and time zone the Cisco CallManager is using.
The softkey template governs the feature buttons available to the user on the bottom of their IP Phone display.
A, B, and C
All of these three methods allow you to obtain the MAC address of the Cisco IP Phone. Although the phone does also support a web interface where the MAC address can be found, it does not support Telnet capabilities.
