More Information

As communicated previously in MC896706 about the retirement of CNS Service API support for older Android clients, this retirement impacts Microsoft Teams devices including Teams Phone devices. To avoid disruption, an update to Teams phone application version 1449/1.0.94.2023082303 or greater is required for Teams Phone devices. These updates must be completed before January 15, 2024, to avoid disruption. Teams devices are governed by the Modern Lifecycle Policy and require users to stay on the most up-to-date version of the Teams phone devices application. Automatic updates ensure that users have the latest capabilities, performance and security enhancements, and service reliability. When will this happen: On January 15, 2025 (previously by the end of September 2024), Microsoft will stop supporting the legacy services infrastructure for chat messaging, impacting Teams Phone devices on app versions earlier than 1449/1.0.94.2024011003. How this will affect your organization: The retirement of the CNS service API incoming calls, voicemail and missed call notifications scenarios on Teams Phone devices. Teams Phone devices app versions 1449/1.0.94.2024011003 and later are not impacted. Update Teams Phone devices to latest Teams Phone app or an app version greater than 1449/1.0.94.2024011003. Manual update process In the Teams admin center, select the device category under Teams devices. Select all respective devices from the list and then select Update. Under Manual updates, select the Teams application and then select the Update button to update to the latest app. If all your devices are eligible to receive automatic updates, use that option to get the latest Teams app version. Automatic update process To help bring the devices to the latest versions, automatic updates will continue at an accelerated pace to ensure adherence to the retirement timeline. Updates can include both firmware and Teams app updates, as applicable to bring the device to the latest versions. These updates will be scheduled outside of normal business hours in the local time of the device, to help minimize impact to your organization. Since it is important that the devices get updated as soon as possible, we will not adhere to the configured maintenance window for the devices. For organizations with users around the globe, we recognize that "outside of normal business hours" might affect you differently. We apologize for the impact this may have on your users.
