Add a read/unread status indicator for voicemail messages that reflects whether any user within the organization has listened to the voicemail, not just the assigned user.

Voicemails should automatically be marked as read once any authorized user in the account listens to them.

If no one has listened, the voicemail should remain unread.

This should apply across shared inboxes or team environments to improve visibility and avoid duplicate follow-ups.

In team settings where multiple users handle calls and voicemails, it’s important to know if a message has already been reviewed. Currently, this can lead to confusion or duplicate work since the system does not reflect team-wide activity.
