Which statement best describes the most deployed stage of VOIP 911?

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

Answer: (B)

VoIP E911 deployment progresses in stages to reflect how widely the capabilities are implemented and used. The statement that describes the most deployed stage is best because it points to the current reality: this stage has achieved broad, practical adoption across providers and PSAPs, representing what most users actually experience today. The other descriptions refer to earlier or transitional concepts—an initial interfacing with the wireline E911 network, a migratory bridging solution, or a historical FCC rule. Those are about past steps or regulatory milestones, not the present, widely deployed configuration.
