Hi ​@FFVIIVince10 
 

RingCentral does not have a built-in feature that allows you to set up a specific notification (like a pop-up alert or sound) when a contact who is currently offline changes their status to online. You would need to manually check their presence status in your contacts or message list.

This is a feature that many users have expressed interest in! Good news, there's already a submitted idea for this. If you'd find this feature valuable, please show your support by voting for the existing feature request on our Ideas Portal:

• Presence Status Change Notification: https://ideas.ringcentral.com/forums/958493-phone-messaging/suggestions/48016169-presence-status-change-notification

Our product team actively reviews these submissions and the number of votes helps prioritize future enhancements!
