If the Teams admin center shows a policy and the shell shows another, believe the shell long enough to place a test call, then refresh both.Replication delay is real.An hour of firmware changes during that delay is not.
Write down the time, the cmdlet, and the values.That note is the evidence pack.It is also how you avoid changing three systems because one screen was stale.
If the portal and the shell disagree, read the shell, wait, and place one test call.
Signaling for When the portal and the shell disagree. Teams keeps the dialog. A 488 is codecs, not a greeting.Teaching order during an incident. Counts in this drawing are teaching order, not customers.
Which description of Set-CsOnlinePSTNGateway is accurate?
Changes settings on a paired SBC, including media bypass and SIP signaling options documented for that cmdlet. 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.

Shows the paired gateways and the status fields the module returns. Confirm the parameter set with Get-Help in the module version you have.

Maintains the tenant’s list of PSTN usage names. 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.

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
Three changes land during a replication delay and nobody knows which one worked.
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.
