Chapter 91 Cisco Unified IP Phone Configuration
Phone Configuration Settings
Key Size (Bits) For this setting that is used for CAPF, choose the key size for the certificate from the
drop-down list box. The default setting equals 1024. Other options include 512 and 2048.
If you choose a higher key size than the default setting, the phones take longer to generate the
entropy that is required to generate the keys. Key generation, which is set at low priority,
allows the phone to function while the action occurs. Depending on the phone model, you may
notice that key generation takes up to 30 or more minutes to complete.
Note The CAPF settings that are configured in the Phone Security Profile window interact
with the CAPF parameters that are configured in the Phone Configuration window.
Operation Completes by This field, which supports the Install/Upgrade, Delete, and Troubleshoot Certificate Operation
options, specifies the date and time in which you must complete the operation.
The values that display apply for the publisher database server.
Certificate Operation Status This field displays the progress of the certificate operation; for example, <operation type>
pending, failed, or successful, where operating type equals the Install/Upgrade, Delete, or
Troubleshoot Certificate Operation options. You cannot change the information that displays
