Zoom Phone users can share a voicemail they own with an internal phone user, call queue, or shared line group in the same account. When sharing a voicemail, you're forwarding a copy of the voicemail to another user. If the user has different retention policies, their policy settings take effect for the shared voicemail.
The phone user who received the shared voicemail can view the voicemail in the Zoom desktop app, mobile app, or web portal. The voicemail will have the label Shared by following by your display name so they know who shared the voicemail. The voicemail will also be marked as unread for the phone user.
