⚠️ Exam Caveat:
Auto-attendants and call queues each need a resource account — and the resource account needs a Teams Phone Resource Account license
Calling Plans are the simplest but have limited country availability — Direct Routing or Operator Connect for broader coverage
Direct Routing requires a certified SBC (Session Border Controller) connected via SIP trunk
Emergency calling policies are required for compliance in many regions — know dynamic emergency calling for Teams Phone
Call queue routing methods: Attendant rings all agents simultaneously; Serial rings agents in order; Round robin distributes evenly; Longest idle routes to the agent who has been idle the longest
