Selective Routing is the process by which 9-1-1 calls are routed to the appropriate PSAP.

• A. A method of identifying caller location.
• B. The mechanism that directs 9-1-1 calls to the correct Public Safety Answering Point (PSAP) based on routing criteria.
• C. A feature that blocks telemarketing.
• D. A procedure to assign ESN.

Answer: (B)

Selective Routing is the mechanism that directs 9-1-1 calls to the correct Public Safety Answering Point (PSAP) based on routing criteria. It uses location data and ESN mappings to determine which PSAP is responsible for the caller, ensuring the emergency is handled by the appropriate agency. This is distinct from simply identifying a caller’s location, blocking telemarketing, or just assigning an ESN—the routing process sits at the level of delivering the call to the right PSAP using predefined criteria.
