MS-721 Question #181: Real Exam Question with Answer & Explanation

Question

You have a Microsoft Teams Phone deployment that is used in the United States. You need to ensure that emergency calls placed to 9911 are routed to 911 and flagged appropriately. What should you configure?

Options

• Aan emergency call routing policy
• Ban outbound PSTN number translation rule
• Ca dial plan normalization rule
• Dan emergency calling policy

Explanation

An emergency call routing policy is the correct tool to reroute a misdialed emergency number like 9911 to the correct 911 number and flag it as an emergency call in Teams Phone. This policy provides both number translation and emergency-specific routing logic.

Common mistakes.

• B. An outbound PSTN number translation rule translates dialed numbers to E.164 format for general call routing but does not provide emergency-specific routing logic or flag the call as an emergency to the PSTN gateway.
• C. A dial plan normalization rule converts locally dialed numbers to E.164 format for standard calls but cannot flag a call as an emergency or route it to a designated emergency PSTN gateway.
• D. An emergency calling policy configures notification settings such as alerting a security desk and enabling location sharing, but it does not control how the emergency number is dialed, translated, or routed to the PSTN.
