Explanation

Microsoft Teams Phone Standard (E) is required because Direct Routing is a Microsoft Teams Phone feature - it lets organizations connect their own telephony infrastructure (SBC) to Teams, but users must have the Teams Phone add-on to make/receive PSTN calls. Office 365 E3 does not include Teams Phone, so this license bridges that gap.

Why the distractors fail:

• A & C (Calling Plans): These are Microsoft-hosted PSTN services - Direct Routing is specifically chosen instead of Calling Plans (often because companies have existing SBC/carrier contracts), so assigning a Calling Plan defeats the purpose.
• B (Virtual User): This license is for resource accounts (auto attendants, call queues) - not end users.
• D (Audio Conferencing): This enables dial-in to Teams meetings via PSTN, which is a separate feature unrelated to Direct Routing voice calling.

Memory tip: Think of it this way - Direct Routing = Bring Your Own Carrier, but you still need Microsoft's "phone engine" turned on. That engine is Teams Phone Standard. No Teams Phone license = no PSTN capability, regardless of how your trunk is connected.
