Google Play Services

Goggle Play services were removed from device software. Access to any Google store or Play
service is not allowed.
■
Updating the device's Android software and application is performed via special software
components that either connect to the Teams Admin Center or to AudioCodes' Device
Manager over a secured channel.

Running Android in Kiosk Mode

Android Kiosk Lockdown software 'locks down' Android devices to only allow essential apps by
disabling access to the Home / Launcher. Using Android Kiosk Lockdown software, Android
devices can be converted into public kiosk terminals or secured work devices.
■
Only specific Microsoft apps and AudioCodes-signed apps that were certified and
approved in the certification process c an run in Kiosk mode; even if a malicious user
manages to install a new unauthorized app on the file system, the launcher on the device
will only run those specific approved apps and this cannot be changed in run time (only
with a new software code provided by AudioCodes).
