Look for a Message icon on a line label
The red background indicates that there are new voice messages.
If call forwarding is set up on a line that has new voice messages, the Call Forward icon replaces the Message icon on the line label.
If you have a voicemail and a missed call, you see the Message icon and the missed call icon.
Listen for a stutter tone (if available) from your handset, headset, or speakerphone when you place a call.
The stutter tone is line-specific. You hear it only when using the line that has new voice messages.
You can set up audible message waiting tones using your User Options web pages.
