Microsoft Teams Interpreter agent: is it supported in 1:1 PSTN calls? Admin docs say "not supported", rollout notice says available since Feb 2026

As your issue description is primarily written in English, I will provide my response in English for your convenience. Please feel free to let me know if you would prefer the information in another language.

Dear Luka,

You have identified a genuine documentation inconsistency, and you are right to want it settled in writing before a rollout of this size. Unfortunately, as a forum moderator, I am not able to confirm product supportability or speak on behalf of the product team. My knowledge is based on publicly available documentation, the same as yours.

That said, the documentation currently points one way. Unscheduled 1:1 calls should not be treated as supported for production, and three sources agree:

1. The admin article lists "Unscheduled 1:1 calls (VoIP or Public Switched Telephone Network (PSTN))" under Not supported, with the header scoped to Meetings, and it was updated after the January rollout notice.
2. Set-CsTeamsCallingPolicy -AIInterpreter exists, but its documentation carries an explicit note that the feature has not been released yet and will have no effect whether enabled or disabled.
3. Interpreter is documented operationally only under Set-CsTeamsMeetingPolicy, using -AIInterpreter and -VoiceSimulationInInterpreter.

The calling policy does carry both parameters, so the control surface exists but is currently inert. That suggests calling support is planned rather than shipped.

For reference: Set-CsTeamsCallingPolicy

For a definitive answer, I strongly recommend that your Global Administrator raise a service request and ask for a written supportability statement from the product team. For detailed instructions on how to get support, please refer to Get support - Microsoft 365 admin. If you don't know who your IT administrator is, please refer to this article: How do I find my Microsoft 365 admin? - Microsoft Support 

Include the Message Center ID for the January 2026 announcement, your tenant ID and region, the Teams client version, your Operator Connect provider, the test user licenses, and the conflicting statements. Suggested wording:

Please confirm whether Interpreter agent is generally available and supported for unscheduled 1:1 PSTN calls in a commercial EU tenant using Teams Phone Standard and Operator Connect. The end-user article describes a call experience, while the administrator support matrix lists unscheduled VoIP and PSTN calls as not supported, and the Set-CsTeamsCallingPolicy documentation states that -AIInterpreter has not been released and has no effect when configured. We require a written supportability statement before a 1,300-user production rollout.

In the meantime, scheduling the customer conversation as a Teams meeting is the supported path, since scheduled meetings are explicitly included. I would pilot this first, as the documentation does not state whether a PSTN dial-in participant receives interpretation.

I hope this gives you a clear path forward. Please know that even though I can't directly intervene, directing you to the correct, specialized support is the most effective help I can provide from my position. Thank you for your patience and understanding. Please let me know if you need anything else. Wishing you all the best.
