This guide explains how to access voicemail, check messages by phone, forward your phone, and clear deleted voicemail messages when your mailbox is full.

🔐 Before You Begin

  • 🌐 You must be connected to the CSHL network or VPN to use the voicemail web tools.

  • 🏢 Community phone extensions do not have voicemail and are not assigned to individual users, so they cannot be managed online.
