Claims citing this source

• Microsoft documentation is inconsistent on outbound PSTN from a Teams Phone extensibility resource account: the quickstart tells admins who plan outbound calls to assign a Microsoft Teams Calling Plan, while the connectivity-cost page says Calling Plan licenses on resource accounts no longer support on-behalf-of or server-initiated outbound calls since 1 November 2025 and a Pay-As-You-Go Calling Plan is required. disputed in context
• The Teams Phone extensibility quickstart says the Azure Communication Services resource's data location should match the Teams tenant location to comply with data boundary regulations. fact in context
• The Teams Phone extensibility quickstart has Teams admins provision the resource account with Teams PowerShell cmdlets (New-CsOnlineApplicationInstance, then Set-CsOnlineApplicationInstance with -AcsResourceId, then Sync-CsOnlineApplicationInstance) and states that Teams Admin Center is out of scope for this step. fact in context
• The Microsoft Graph API that CCaaS developers use to list Teams resource accounts for Teams Phone extensibility (admin/teams/resourceAccounts) appears in the quickstart on the beta endpoint, which Microsoft says is not supported for production use. fact in context
• For Teams Phone extensibility, the resource account ApplicationId must be the CCaaS provider's third-party bot ID; Teams first-party application IDs do not work. fact in context
