I have no idea how this is possible. I doubt it is, but I'm going to die trying to do this.

I had a sound recorded by a voice-over company. I have the file as .wav and .mp3. I want to set this file as my voicemail.

Can anyone think of any way at all to do this except for recording it off regular speakers as if you were talking, setting your voicemail.

I have the treo 800w.
