Here is an excerpt from Cisco Press
Configurable Display of Forwarded Call Information
You can specify, on a per-line basis, the types of information that users see when calls are forwarded to their stations. Each line on a station can display different forwarded call information based on the settings configured in the Forwarded Call Information Display area on the Directory Number Configuration page in CallManager Administration (Device > Phone > find and select a phone > click a line number).
To better understand the display capabilities that can be configured for each line on a station, the following explanations help to clarify some common terms.
###Each line on your station that can be used for calls has an associated directory number. If you originate a call, the line that you use to place the call, for display purposes, is referred to as the calling line ID (CLID) or simply calling party number. There is also a display name associated with that line on your station, and it is referred to as the calling name ID (CNID) or simply the calling party name.
When you make a call by dialing the directory number of the person you want to reach, the number that you dial is referred to as the original dialed number (ODN). Because calls might be forwarded one or more times, the original dialed number might not be the actual number of the line that is answered when the call is completed. The final directory number used to extend the call when the call is actually completed is referred to as the redirected dialed number (RDN).
The following check boxes are provided on the Directory Number Configuration page in CallManager Administration. All can be enabled or disabled by selecting/deselecting the check box. These check boxes control the display of information for calls that have been forwarded to the phone. By default, for forwarded calls that arrive at your phone, you will see the original dialed number and the calling party name.
*Caller name (also known as calling name ID [CNID])— Enabled by default
*Caller number (also known as calling line ID [CLID])— Disabled by default
*Redirected number (also known as redirected dialed number [RDN])— Disabled by default
*Dialed number (also known as original dialed number [ODN])— Enabled by default
Consider the following example: A call arrives at John's station on the line associated with directory number 4444. Delon Whetten originated the call on line 1111, and called Anne Smith at 2222. Anne had forwarded 2222 to Chris Pearce at 3333. Chris had forwarded 3333 to you at 4444. In this example, the calling party name is Delon, and the calling party number is 1111. The original dialed number is 2222. The redirected dialed number is 3333. When the phone arrives at John's station, the information that displays depends on the display options that you configured for John's station.
