07 · Attendants and queues
The number’s owner decides whether the company keeps it when a human leaves.
Put service numbers on resource accounts. Do not put the main number on a receptionist’s user object. Caller ID for the queue should be chosen, not inherited from whoever built the queue.
How you get the number depends on the connectivity option: Microsoft inventory, the Operator Connect carrier, or the Direct Routing carrier. Porting is a carrier project with a date, not a PowerShell metaphor.
Assign the company number to a resource account, and set caller ID on purpose.
Service numbers sit on resource accounts. Caller ID is a choice.
If it fails: The receptionist leaves and the main number is released with their user.
A colleague reports: The schedule says five agents and three have opted out. Where do you start?
The schedule says five agents and three have opted out. Pick one policy and tell the supervisors. Source: https://learn.microsoft.com/en-us/microsoftteams/create-a-phone-system-call-queue accessed 2026-10-14.
Which description of Callback is accurate?
A queue feature that calls the customer back. The prerequisite article treats callback as a case that needs funding on the resource account. Callback is an outbound PSTN call, not a setting with no carrier. Source: https://learn.microsoft.com/en-us/microsoftteams/aa-cq-reference-prerequisites-licensing accessed 2026-10-14.
A colleague reports: The option is on and every callback fails. Where do you start?
The option is on and every callback fails. Fund pay-as-you-go or credits, then test one callback. Source: https://learn.microsoft.com/en-us/microsoftteams/aa-cq-reference-prerequisites-licensing accessed 2026-10-14.
Around the call: compliance recording, workforce management, emergency location, analytics, CRM screen pop, and an agent with a human escape. Each one has its own failure.
The receptionist leaves and the main number is released with their user.
Cisco CUBE is one of the SBC families named in this lab’s certification lesson. A certified release can be the Direct Routing SBC between Unified CM and Teams.
The tenant still needs a verified domain on the SBC FQDN, and the user still needs Teams Phone. The studio translator does not open a live AXL session. Confirm the current certified release before you build.
Teams Phone and Webex Calling are separate clouds. This lab does not describe a feature that registers a Webex Calling user into a Teams tenant.
A number move is usually a carrier port, a certified SBC, or a meetings interop product. Confirm before relying.
Unified CCE stays the ACD until you migrate it. Microsoft’s contact-center articles name Connect, Extend, and Unify. They do not name a UCCE connector in the notes this lab cites.
Voice into Teams is still Direct Routing or Operator Connect. The routing script stays on the contact-center product you bought. Confirm the vendor’s current model. Source: https://learn.microsoft.com/en-us/microsoftteams/teams-contact-center.
Copilot Studio, Azure Communication Services, and Graph are later tracks in this lab. Treat any uncited limit as confirm before relying.
Opened 2026-10. A row marked confirm did not open. Wikipedia is background. The Teams blog row is the community index.
