Installed .4 today, .3 yesteday, coming from 1.0 (working smooth so I didn't go to 1.1). My corporate voicemail will email me my voicemails as wav attachments - I don't remember the vm storage servers manufacturer, but I'm leaning towards it being an avaya. Anyways, with 1.0 I could download and open the wav attachments and play them back, no problem. On .4, I'm getting the "not supported format" error. Since I know that the type of wav being used hasn't changed - any ideas on why this is popping up as a problem in .4?
