Which device specifically records the identifiers of cellular phones?

The telecommunication identification interception device is specifically designed to record the identifiers of cellular phones. This device captures information such as the unique identifiers associated with mobile devices, allowing for the monitoring of communications related to specific phones. This is crucial in law enforcement and intelligence contexts, where tracking the movements and communications of particular individuals using their cellular devices is often necessary.

The other devices mentioned serve different purposes. A pen register records outgoing dialing numbers but does not capture identifiers. A trap and trace device identifies the incoming numbers to a specific line but again does not focus on cellular identifiers. Mobile communication tracking information may refer more generally to various methods of tracking mobile devices, but it is not the specific term used for the device that records identifiers as is the case with the telecommunication identification interception device. This focused functionality makes the correct answer particularly suitable for the question.
