mVoiceMail enables you to play voicemail messages that you receive attached to regular e-mails on your Treo 700w device.
mVoiceMail is an advanced player for WAV files attached to e-mail messages. Many mobile service providers allow you to configure voicemail service on your land line at the office or home to be forwarded to your regular e-mail account as WAV files. When this setup is in place and someone leaves a voicemail you will receive an e-mail with voicemail attached as an encoded WAV file - and you can use mVoiceMail to play it.
mVoiceMail is implemented as an OS extension enabling you to play sound files in WAV format from any application that can properly handle file attachments.
mVoiceMail also allows for voicemail messages to be saved directly on and played from the SD card. This feature prevents potential compatibility issues with e-mail clients.
