Mobile Device Management (MDM)

If you use ProCall Mobile in conjunction with a Mobile Device Management (MDM) such as Microsoft Intune, you will not be able to access the Android phone settings and thus the changes to the call account permissions. The following alternatives can be used for activation or deactivation: ProCall Mobile app: Android call account notes..

The Android call window cannot be used within the Android work profile (MDM). As soon as a softphone call is made, the user leaves the work profile. This results in undesired behavior, such as the calls being saved in the phone's call log.
