does anyone know of any reason why the Treo would have problems opening a wav file being emailed from IP office voicemail pro. Seems like a Treo problem, but if it can be fixed simply on my system, why not? The user can save the file and play it, but they can't open it from the email and play it. Can I change the vmail pro file settings for the attachments? Should I just tell the customer to call Treo?
