What uniquely identifies a wireless emergency call?

Access tandem
CAMA
ESRK
ANI

The correct answer is: ANI

The correct choice is ESRK, which stands for Emergency Services Routing Key. This identifier is significant because it is used in the context of wireless emergency 911 calls to route the call accurately to the appropriate emergency services. The ESRK is particularly important as it encompasses details necessary for successful transmission and routing of the call, including the location of the caller and the designated emergency services. While the other terms may be related to telecommunications and emergency services, they do not specifically designate the unique routing mechanism used for wireless emergency calls. For instance, ANI refers to Automatic Number Identification, which delivers the caller’s phone number to the emergency dispatcher but does not encompass the routing requirements unique to wireless calls. CAMA is a type of analog signaling used primarily for emergency calling but lacks the specific context of routing found in ESRK. Access tandem pertains to the circuit switching aspect of telephone networks but does not uniquely identify wireless emergency calls.
