Microsoft Teams: Line key configuration on Teams Phone devices from Teams Admin Center (TAC)

🚨 The Signal: Admins will gain granular control over Teams Phone line key configurations, including speed dial and shared lines. This enhances device management but introduces new configuration points for potential misuse if not secured.

The Impact

Admins and Security Teams are affected by new configuration options that, if mismanaged, could expose call information or create unauthorized access points.

• Admins: New configuration options for Teams Phone devices.
• Security Teams: Need to review and secure new device settings.
• End Users: Potential for misconfigured speed dials or shared lines.
• Organisations: Risk of information disclosure if not properly secured.

The Action

1. Review Microsoft's documentation on Teams Phone line key configuration best practices upon release.
2. Develop and implement a policy for configuring line keys on personal and common area phones.
3. Audit existing Teams Phone device configurations for security and compliance post-rollout.
4. Train IT and security staff on secure configuration of new line key features.
