What type of information does the WPH1 display provide?

The WPH1 display is designed to provide critical information regarding calls made to emergency services, particularly those originating from mobile devices. The correct choice highlights that the WPH1 display shows the caller's phone number and the cell site location. This information is vital for law enforcement and emergency responders as it helps them quickly identify where the call is coming from and enables them to coordinate an appropriate response, especially in situations where the caller may not be able to provide their location directly.

Understanding the specifics of the WPH1 display is essential for handling emergency communications effectively, as it allows for quicker dispatch of resources and enhances the ability to respond to incidents in real time.
