Explanation
Direct Routing requires the Microsoft 365 Phone System license (E) because Phone System is what enables the PBX features in Teams (call control, voicemail, dial plans, etc.). Office 365 E3 does not include Phone System. Critically, Direct Routing does not require a Calling Plan (C or D) - the whole point of Direct Routing is that you bring your own PSTN carrier via a certified Session Border Controller, bypassing Microsoft's calling plans entirely. The Virtual User license (B) is for resource accounts used with auto attendants and call queues, not for end users. Auto Conferencing (A) is a separate add-on for dial-in meeting bridges and is unrelated to Direct Routing voice calling.
