This document discusses how to display the caller line identification in the window of the calling phone. When a call routes through a translation or route pattern, routes to a Call Forward All or Call Forward Busy destination, or is redirected through a call transfer or CTI application, the connected number display updates to show the modified number or redirected number.
Cisco recommends that you have knowledge of Cisco CallManager.

The number displayed in the phone window of the caller changes when the call connects.
When a call routes through a translation or route pattern, routes to a Call Forward All or Call Forward Busy destination, or is redirected through a call transfer or CTI application, the connected number display updates to show the modified number or redirected number.
In Cisco CallManager 4.2(3) and later, the connected number display can be turned off . This option addresses customer privacy issues as well as connected number displays that are meaningless to phone users.
As an Administrator, complete these steps in order to turn off phone display updates, so the phone displays only the dialed digits:
Choose Service > Service Parameters in the Cisco Unified CallManager Administration page.
Choose the server where the Cisco CallManager service runs, and then choose the Cisco CallManager service.
In Clusterwide Parameters (Device - General) change the parameter value of Always Display Original Dialed Number to true. The default setting is false.
