Personal Directory (PD), Callers list, and Redial list are intertwined within the digital stations that support this capability (redial and callers only on the 3903, but redial, callers, and directory on the 3904 and 3905) or PD data on PPM (UNIStim).

The Redial List is a call log feature. The content of the list is generated during call processing. You cannot modify this content. However, you can delete or, in some cases, copy entries to the Personal Directory.

The 3903 phone has a greatly reduced capacity for storing this data. The following is the Redial list size:

Redial List supports the following for devices that support Personal Directory:

PPM stores the most recent 100 call log entries, which are saved in the format of one entry per one call format. When the device is logged in, the saved call log entries are separated into Callers and Redial list.

This is invisible to Communication Manager. It is handled either by the telephone itself (3904) or Device Adapter (UNIStim).

Redial lists are an automatic feature of certain digital and UNIStim stations. Stations with a display and the Directory or Log button can provide a trail of called and calling parties and can copy entries from either the called (Redial list) or calling party (Callers list) lists into a personal directory. This application is completely independent of any corporate directories.

Note that 39xx stations with this capability handle it completely internal to the phone. For added robustness, the UNIStim stations supporting this provide it using the PPM as the data warehouse. This permits the PPM call history to survive a reboot of the station.
