Source note · Wrong or missing caller ID on outbound calls
With Unified CM's External Presentation Name and Number feature, the From header carries the configured presentation name and number for display only, while PAID (and Remote-Party-ID) carries the user's real identity, such as the DN or DDI, for billing.

The PAID header contains the identity (original DN or DDI) of the user.
