My company utilizes a voicemail system which sends audio files as email attachments. These audio files playback via QuickTime in iOS which pushes the audio out via the phone's speaker. Which is great for a Mumford and Sons song, not so great for voicemail. I can hook up headphones for private listening, but when I am without headphones wanted to use the phone's ear speaker instead.
Using an iPhone 5 and iOS 6 is it possible to play audio files played back via QuickTime with the ear speaker? If not via QuickTime is there an app for that?
