The voicemail icon is always showing a red dot that never goes away

Hi,

I’m by no means qualified to answer your question this evening but I will still attempt to help by suggesting a work-around for time being.

I’ve experienced similar bugs on previous generations of iOS.

Have you tried deleting all audio recordings that are currently stored in your phones Voicemail?

View Voicemails and select “Edit”

Select all current audio messages that are stored in your phones Voicemail and delete them from your Voicemail home UI.

This can be achieved by simply tapping the empty bubble left of the Contact’s name so that the message is highlighted grey and then selecting the blue text at the bottom right-hand side of the screen that says “Delete”.

If done correctly your Voicemail inbox should appear to empty at first glance. In the event you find yourself deleting a Voicemail you did not intended to remove, don’t worry.

You can always restore the recently removed Voicemails as shown below.
