Why aren't my calls forwarding? What happens during call routing hours when I'm using the desktop app?
If you are logged into the desktop app, calls are presented to the desktop user irrespective of the call routing hours.
To avoid ringing on the desktop client, Do Not Disturb needs to be activated from the desktop app. To activate this, click Settings in the top right hand corner and then select the Do not disturb button in the drop-down until it turns green.
Calls will still take 30 secs to go to the voicemail irrespective of the call routing settings.
