06 · Routing and dial plans
Routes match the number after the dial plan. A perfect route that expects E.164 will never see a local habit.
The person dials 020 7555 4010 or 425 555 0100. The first matching normalization rule rewrites it. Later rules do not run. The voice route then sees the result, usually E.164.
Put emergency short codes above any catch-all. A rule that turns every three-digit string into an extension will eat 999. Test the raw digits and the normalized form. The route is not wrong just because you typed the raw digits into it.
Normalize first, first match wins, then let the voice route see E.164.
First matching normalization rule wins. I test the route with the normalized number.
If it fails: A catch-all rule is first, so the emergency rule never runs.
Which description of Normalization is accurate?
The dial plan rewrites what a person dialed into a number the routes can match, usually E.164. The first matching rule wins. A route for +44 will never see 020. Source: https://learn.microsoft.com/en-us/microsoftteams/create-and-manage-dial-plans accessed 2026-10-14.
A colleague reports: A catch-all rule is first, so the emergency rule never runs. Where do you start?
A catch-all rule is first, so the emergency rule never runs. Put the specific rules above the general ones. Source: https://learn.microsoft.com/en-us/microsoftteams/create-and-manage-dial-plans accessed 2026-10-14.
Which description of Tenant dial plan is accurate?
A set of normalization rules you assign to users. A user can have a more specific plan than the tenant default. Two sites that dial local numbers differently need two plans, not one heroic route.

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.
A catch-all rule is first, so the emergency rule never runs.
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.
