Configuring Time Zone on Teams Devices

AudioCodes recommends using Geolocation as the time zone configuration method.
Geolocation is the default setting, if no other changes to the time zone settings are made, the device retrieves the time from it's geographical location.

Manual time zone setting is NOT recommended. Choosing a time zone manually may cause retrieval of the incorrect time zone, and cause functionality issues.

You can configure the time zone using one of the following methods, which are listed in order of preference for best performance:

Geolocation (Default):
The default geolocation method uses a devices public IP address to obtain it's location. If the devices are behind NAT they are using STUN server to discover their public IP addresses.
A common STUN server example is Google's publicly accessible server: stun.l.google.com:19302 (default URL).
DHCP Option 100/101 (posix/tzdbx):
Configuration is obtained from DHCP server.
Admin Provisioning:

Use one of the following:

Teams Admin Center, created under configuration profile.
Device Manager, created in configuration parameters setup.

The supported parameters for Device Manager configuration can be found in product specific Admin and User guides. For Teams Admin Center refer to Microsoft documentation > Configuration profile.
