Additional meeting and call-related features and issues within Microsoft Teams for business
Hi @Rajasekar K,
Thank you for laying out the scenario. I hope I can share a few ideas that may help explain what you’re seeing.
Since this behavior is occurring after November 2025, it may be related to recent changes in how Microsoft handles outbound PSTN calls made on behalf of Call Queues or Auto Attendants. In some scenarios, outbound OBO (on‑behalf‑of) calls might not function as expected if the resource account is using a standard Calling Plan license.
To support outbound calls when users choose Call as Call Queue or Call as Auto Attendant, it’s often recommended to assign a Pay‑As‑You‑Go Calling Plan to the resource account. This allows Microsoft Teams to meter and charge outbound calls on a per‑minute basis, which aligns more closely with OBO calling requirements in Call Queue or Auto Attendant scenarios. Depending on your tenant configuration, this plan can be added alongside, or in place of, the existing Calling Plan.

Additionally, it’s worth checking one more setting in your tenant. In the Microsoft 365 admin center, go to Billing > Your products, open the Teams Phone with Calling Plan license, and scroll to the very bottom. There you’ll see Phone service consumption. Please make sure this setting is switched to On, as it’s disabled by default and is required for consumption‑based calling scenarios like this.
