Problem setting the LED notification for voicemail - Cisco 7811/6821

[tacpwd2015]

Hi everyone, hope this message finds you well.

I've got a doubt with some Cisco IP Phones 7811 & 6821 series. I'm trying to set the LED notifications for the voicemail unlistened messages, so I found this option at the advanced mode > Voice > User tab:

What option?

I'm Sorry, Andrew, my last post didn't show correctly. This is the option I found:

So, the problem is that, if I set the Voicemail option (in fact, that is the default option) the LED doesn't turn on when receiving unlistened voicemails. But if I choose the second option "Voicemail, Missed Call", the feature works only with missed calls.

Is this correct? Or which option should I choose if I want this LED to notify me about voicemails?

Thanks for your help and have a great day!
