Voicemail message waiting indicator (MWI) slow to show up/turn off

[Ansextra]

The good news is that I forward my voicemails to my email and still know immediately when a voicemail is left. I have a special sound set up on my Android phone to alert me of voicemail alerts. I also see it immediately in Gmail on my desktop as well if I happen to be sitting there.

Delays are back for me. It just took 4 minutes for the voicemail indicator to show up on my phone after receiving a message. It also took another 4 minutes for the indicator to disappear after I listened to and deleted the message.
