Genesys Cloud provides functionality to filter voicemails within personal or group voicemail boxes. Users with the Communicate - User role can access their voicemail box and utilize the Show All option to view all messages. The platform enables filtering capabilities to display only read or unread voicemails, with the button name dynamically updating based on the selected filter preference. Users can also select specific group voicemail boxes from a list to view messages associated with those groups. Access to these features requires the Voicemail > Voicemail > Receive permission, which is included in the Communicate - User role. Key capabilities include accessing personal or group voicemail boxes, filtering messages by read/unread status, and specifying which group boxes to view.
