In our setup, the term "agent" in Talkdesk simply refers to an employee or staff member handling inbound and outbound calls. Since each user makes calls and needs to receive return calls through our main number, is it possible to assign a voicemail to each user? Or are voicemails distributed based on the user's name? I'm trying to understand how individual users are notified of voicemails that require their attention. When a voicemail is received, does the user get a specific notification, or is the notification sent to the entire team?
