Which term describes a transitional approach to VOIP 911 deployment?

• A. Migratory solution
• B. The most deployed stage of VOIP 911
• C. First deployment stage interfacing the E911 wireline network
• D. FCC Report and Order 94-102

Answer: (A)

A migratory solution is the transitional approach to VOIP 911 deployment. It describes an interim, phased method that uses the existing E911 infrastructure and routing while gradually adding VOIP-specific features, such as accurate caller location data (ANI/ALI) and PSAP connectivity, until full NG911 capabilities are in place. This approach lets providers and PSAPs roll out 911 services without a disruptive, all-at-once migration, giving time for testing, coordination, and regulatory alignment. The other options don’t fit as well: one describes an undefined stage rather than a defined transitional method; another refers to an early deployment step rather than the overall transitional strategy; and the FCC order is a regulatory document, not the deployment approach itself.
