Caller ID

Caller ID (also known as reverse-aliasing) allows the receiving radio-user to identify the source-radio of a transmission. When an incoming call's Call ID exists in the receiving radio's Unified Call List (UCL), the UCL's Contact Name and Call ID appear in the receiving radio's display, thus identifying the caller. If the contact information does not exist in the UCL for a receiving radio, then the Radio ID of the caller's current channel appears in the receiving radio's display.
