Microsoft Graph now includes APIs that support Teams administration scenarios through beta:

• Teams User Configuration API - Available through V1.0
• Number Management APIs - Available through beta

These APIs enable programmatic access to user configurations, telephone number management, and policy assignments—helping organizations automate and scale Teams management. They are designed to support extensibility, automation, and integrations with your existing tools and workflows.

Please note that only Teams User Configuration API is currently available via the Microsoft Graph through V1.0, rest of the two APIs (Number Management and Policy Assignment) are currently available via the Microsoft Graph through beta. They are supported in commercial environments and accessible through both delegated and application permissions.
