What the models said for it

Verbatim evidence the judge attached to positive labels.

“You're already deeply standardized on Microsoft 365 and Teams: evaluate Teams Phone first.” GPT-6 Luna · Business phones · paraphrase prompt · alternative

“Microsoft Teams is where employees already work: evaluate Teams Phone.” GPT-6 Luna · Business phones · direct prompt · alternative

And against it

Verbatim evidence attached to negative labels. A warning on a product with few labels is a warning; on a product with many, it is one voice among them.

“Teams Phone if you expect a plug-and-play phone system... can involve extra setup and licensing” GPT-6 Luna · Business phones · negative prompt · soft negative

“Best if deeply embedded in M365, but evaluate voice feature gaps carefully.” Kimi K2 · Business phones · scale prompt · soft negative

What carried it into the answer

The sites and pages cited by the answers that named Teams Phone. A fact about retrieval, not a lever on the model.

Citations exist only for the models that return a source list, five of the fourteen in this edition, so these counts come from 6 of the 7 answers that named Teams Phone and are not a share of its labels.
