Download a fresh copy of beta 4 and install it. I am not experiencing anything like that on my device while running iOS 9 beta 4 and I haven't read about this happening from any other users except you. It's possible that something became corrupted after the install.
I read on the public beta 2 thread a few people are having problems with visual voicemail. I don't know if it's the same build number as beta 4.
