[FONT=Calibri]We have ~ 100 Blackberries on our BES. Six different models from five different wireless providers. We started getting complaints that our employees were having problems playing their voicemails from our corporate phone system. They used to just click open attachment (.wav) and the voicemail would play. Now they get a message to either to preview or download. When I checked the BES, everyone that is complaining has upgraded to 4.5.x I compared my Blackberry with a person having this problem. We both have Sprint BB Curves. My BB is running and his is running I sent a test VM to both of our email. My BB plays the .wav just fine. His BB pops a screen asking to preview or download. I have searched and found several Threads asking this question, but no answers.[/FONT]
