Set up Call Alerts for Group Voicemail
Cloud Voice can place outbound notification calls whenever a shared group voicemail box receives a new message. You define an ordered list of external numbers, and the system dials them in priority order until someone listens to the pending messages or the call cycle limit is reached. This is a good fit for after-hours or emergency lines: route the incoming calls straight to a group voicemail, and let the alert calls reach your on-call team instead of leaving them to watch the mailbox.
When to use this
Section titled “When to use this”Suppose a support team handles after-hours emergencies but does not want to staff a live queue overnight. You can point an inbound route for those calls at a dedicated group voicemail, then enable call alerts on that box. Each time a caller leaves a message, Cloud Voice rings your on-call agents so they can respond right away.
