Pair a lab SBC to a lab domain.Use obviously fake names.Contoso and 555 numbers exist so practice does not point at a real directory.Do not find-and-replace a lab script onto production without reading every name.
Production changes get one hypothesis, a rollback, and a window.The lab is where you learn that a private CA will not satisfy Direct Routing.
Experiment in a lab tenant.Do not point a practice script at production by find-and-replace.
Attendant distribution for Safety on a lab tenant. Overflow is a configured target.Lab first. Counts in this drawing are teaching order, not customers.
Which description of New-CsOnlineVoiceRoute is accurate?
Creates a voice route with a number pattern and one or more gateways. Confirm the parameter set with Get-Help in the module version you have. Interviewers ask for the object model more than for a memorized script. A wrong parameter against production is not a lab.

Which description of New-CsOnlineVoiceRoutingPolicy is accurate?
Creates a policy whose ordered PSTN usages a user is allowed to match. Confirm the parameter set with Get-Help in the module version you have. Interviewers ask for the object model more than for a memorized script. A wrong parameter against production is not a lab.

Which description of Grant-CsOnlineVoiceRoutingPolicy is accurate?
Assigns a voice routing policy to a user. Confirm the parameter set with Get-Help in the module version you have. Interviewers ask for the object model more than for a memorized script. A wrong parameter against production is not a lab. Source: https://learn.microsoft.com/en-us/microsoftteams/direct-routing-plan accessed 2026-10-14.
Effective policy The policy the user actually has after direct assignment and group assignment are resolved. The one you edited may not be it. Config: Read the effective value before and after the change. Fault: You update a policy that is not assigned.
Lab tenant A tenant that is not production. Pair a lab SBC there. Do not discover certificate behavior on the company trunk. Config: Keep lab domains and lab certificates obvious. Fault: A lab FQDN is the production FQDN.
Get-Help before Set Cmdlet parameters move between MicrosoftTeams module versions. Read help in the version you are about to run. Config: Get-Help cmdlet -Parameter * in the lab. Fault: A script from last year removes a number.
Group policy assignment Many Teams policies, including compliance recording, can target a group. Membership changes the effective policy without a click on the user. Config: Read the effective policy after group changes. Fault: Recording starts for people who were only added to a mail group.
Sister technologies
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.
Config and troubleshooting
The lab FQDN is also the production FQDN.
Cross-platform bridges
CUCM
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.
Webex
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.
UCCE
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.
