ESRD may be used to retrieve ALI data with the call. Which statement best reflects this?

• A. ESRD may be used to retrieve ALI data with the call.
• B. ESRD provides only caller's address.
• C. ESRD routes calls without any data.
• D. ESRD is used to store log files.

Answer: (A)

ESRD, the Emergency Services Routing Digit, works with Enhanced 9-1-1 to carry routing information and enable ALI data retrieval during the call. When the call arrives, ESRD tells the system which PSAP boundary applies and allows the ALI database to be queried so the telecommunicator can see the caller’s address and location on screen as the call is answered. This integration means ALI data is retrieved in real time with the call, not fetched later. It’s not simply providing only the caller’s address, it doesn’t route calls without data, and it isn’t used to store log files.
