Decent app but needs improvement – AT&T Voicemail Viewer (Work) Review

Had this app for a while now it works ok but could use some work. When deleting voicemails on phone it doesnt always delete on office phone. It would also be nice if you could mark messages as new after they were listened to. The alert noise for new messages is barely audible, it would be great if you could select your own alert tone and if it had reminder alerts until you check the message. The time stamps on messages are sometimes wrong too.
