Question

Teams Phone mobile AT&T operator connect voice

Cody Coleman 0

I have spent a few hours on the phone with support from AT&T business my operator and they assure me that my number has been enabled and provisioned for teams phone mobile on their side, yet no numbers show in "acquired numbers" in my admin of Teams operator connect.

Microsoft states that all support for operator connect is handled by your operator, but the operator says everything is provisioned and should be displaying in my tenant, as it has been multiple days since the line was provisioned.

KYC has been filed and completed.

Any suggestions would be appreciated.

Dear @Cody Coleman,

Thank you for posting your question in the Microsoft Q&A forum.

Based on your description, AT&T confirms the Teams Phone Mobile number is provisioned and KYC is complete, but no numbers appear under Operator Connect, Acquired numbers in the Teams Admin Center. Microsoft says Operator Connect support is handled by the operator, while AT&T says provisioning is complete.

Try to verify the only valid location for the numbers

Ensure you have eligible Microsoft 365 subscriptions for Teams Phone Mobile.

Go to Teams Admin Center > Voice > Phone numbers to check whether your number phone has been uploaded yet.

It would be helpful if you can provide screenshot of operator connect in your Teams admin center so I can check Whether the Operator Connect relationship is active (Teams admin center > Voice > Operator Connect)

For more detail information, you can refer to these articles:

In the ATT portal my tenant ID is already present and populated correctly so I believe I can rule out that they applied it to the wrong tenant.

I encounter errors on ATT side in their business center which is where I would be able to self service and activate teams phone mobile, however since my account with ATT is only a week old they say it takes some time for everything to propagate on the portals I have access to, so I have relied on ATT reps to activate the service and provision the line on their side, which now a total of three separate reps over the course of of six days have said everything is good to go on their end.

Once the number shows as acquired I think I can take it from there.
