Jabber for Windows 11.8.3. or earlier.
Configure Call Pickup Group with the option to NOT display the calling number.
On deskphones it works very well.
At Jabber Clients the calling number is still displayed in pickup popup window.
Cisco Communication Manager is version 10.5.
Its a bug? Its a feature? Can I hide the calling number in pickup popup at Jabber for windows like at desk phones?
