When I access the grandcentral web site (mobile version) to play my voice mails I am unable to play them by clicking the message link and choosing open from the resulting dialog box. Media player gives me a "File format not supported" error. If I choose to download the file and then open the saved file it plays fine.

Anyone have any ideas why that would be? It' not a huge problem, it just adds a few more steps; but it should work by selecting "open"

The download type is "audio/x-mp3"
