About the only thing I can suggest is this.
Consider the fact that everything on your phone is an Application running on the OS. Each Application can fail due to bugs or whatever.
When an application starts to act up, a good true reboot is in order.
Try a reset/reboot.
Pay close attention to second option it decribes.
To add more info.
A reset/reboot is:
Go to Home Screen
Press and Hold Home Button
Keep holding and press and hold Lock Button
Keep holding Both
You will see Slide to Turn Off (Don't let go to slide, just keep holding)
The phone will turn off (in time, but screen will look like it has some white lines)
When you see the Apple Logo, you can let go.
Turning off via the Slide to Turn off while good and fine to turn off, is more like the Sleep Mode on a computer. Thus any locked up issues in memory remain when you turn back on. A reboot as described is like doing a real Turn off and Turn On on a computer.
It is sort of important to know. When you access an Application then decide to go back to Home Screen. That application doesn't really close, it is just set to standby (stop processing but still in memory where you left it). So if it ever messes up, the bad memory it has is still, well bad.
One can reset an Application by when in that application, press and hold the home button until it forces it closed and returns to home screen. That really kills the application so next time back in it will reload itself.
The reboot is a good option over all as it just reboots the whole phone and OS so if that App messed up memory elsewhere outside of the App, the reboot will fix that as well.
So for me, anytime any app acts up on me, I do a reboot (as described above) and I don't any problems for a long time.

This may sound really stupid but two things, indulge me please:
One: Remove your case (I only ask this because of it happening to two phones)
Two: Visual Voicemail can take a abit to work or download, if edge service is really slow where you are at, it may take a few, be patient and let it isit once the play sign is tapped and the pause sign is showing.
Hope this helps
I'm fairly certain I have the answer! This is caused by the iPhone's *proximity sensor*. The iPhone is assuming that you are listening to your voicemails through the earpeice, and is therefore turning off the screen. To test, simply enter the voicemail section, and place your hand over the earpeice without playing any voicemails... does the screen turn off ? It should.
The phone is simply deactivating the screen, as it is thinking it is located next to your ear.
The phone will not turn off the screen unless it is actually near your ear or the sensor is covered. I have played visual voicemails many times without having the phone next to my ear and the screen does not go blank. What this author is describing is aberrant behavior.
I think that the suggestion that the edge network is to blame is a good one. I have had voicemails disappear when I move into weak network spots, only to reapear again later when I am in a good cell.
I believe that the author is inadvertently placing his/her hand near the proximity sensor.
As simple as that.
While flicking at the screen, it is possible to make the screen 'flick' off/on if your hand or palm enters the sensor range. I'm sure it is inadvertent. But I can't think of any other explanation.
