Which component serves as the core database for call routing and delivery in the NENA i3 solution?

• A. A functional entity that provides locations of endpoints.
• B. A protocol that converts analog to SIP signaling.
• C. The core database for call routing and delivery in the NENA i3 solution.
• D. Provides the border firewall.

Answer: (C)

In NENA i3, routing decisions hinge on a central data store that holds routing rules, endpoint locations, and delivery metadata used to determine how a 9-1-1 call is routed and delivered. This component acts as the single source of truth for where calls should go and how they should reach the correct PSAP, ensuring accurate location information is delivered along with the call path. The other functions—providing endpoint location data, converting analog to SIP signaling, or handling border firewall duties—support the system in different ways but do not serve as the central routing and delivery database.
