When I click on the icon to play the voice mail from the voice mail message list, I get a JavaScript error and the window just freezes. The debugger points to line 125 in VoiceMailPlayer.aspx where it tries to lowercase the cpuClass attribute of the window.navigator object. Unfortunately, on Safari 5.1.2 and Firefox 8.0.1 on Mac OS X 10.7.2, the cpuClass attribute is undefined.
Anyone know of a workaround for this?
