Teams caller ID is not showing the caller's name, only the phone number

[NinjaLee]

Hello,

Teams caller ID is not showing the caller's name, only the phone number. I'm not sure if direct routing to a third party is the issue.

We tried the following with the same results.

1. Added the callers' names & phone numbers as a contact into Outlook and Teams.
2. Added the callers as contacts in Exchange Online.
3. Confirmed that "Scope directory search using an Exchange address book policy" was enabled in Team Admin Portal.

Please advise.

Hi @NinjaLee ,

To update the Called ID name, you should email Microsoft porting team with the list of numbers and CNAMEs at ptn@microsoft.com

From the official documentation:
"By default, the following caller ID settings are turned off. This means that the Teams user's phone number can be seen when that user makes a call to a PSTN phone. You can change these settings"
