Messaging
SMS and shared voicemail
Plan registrations, inbox ownership, co-recipients, notifications, and retention.Treat SMS registration and voice routing as related but separate configurations. A phone number can route calls one way and messages another.
Assign shared voicemail to a role or monitored mailbox instead of one employee whenever continuity matters.
Document who receives alerts, who can open transcripts, how long content is retained, and what happens when an owner leaves.
