3Open the app and grant every permission it asks for (see below)

2Permissions to grant
CallDesk logs and records your work calls for the back office. Grant all of these, or calls won't be captured.
Phone & Call log
Place calls and record which calls happened — Allow
Microphone
Record the call audio for quality review — Allow / While using
Notifications
So you can see the app is running — Allow
3Keep it running
Phones close background apps to save battery — that stops call logging and recording. Pick your phone brand and turn on auto-start and unrestricted battery.

When the back office updates, CallDesk loads the newest pages automatically — no need to clear cache or reinstall. If a page looks wrong, pull down to refresh. This app is for the agent's own work phone only.
