Numerical tally of voicemails on Poly phones

Our users are used to seeing a numeric tally of the voicemails that they have on our old system being displayed on the phone. They are used to looking at the phone screen in the morning and seeing that they have a certain number of voicemails, which helps them plan their morning schedule. This is a very useful feature that they came to depend on with our old carrier. They would like to get this feature back.
