The user would have to forward it to the "email" addy of the next users callpilot "mailbox"....otherwise an "outside" "non subscriber" would have to listen to a .WAV file version through their computer. The only way you could listen over the phone (as I understand it.....) is if it was forwarded to a callpilot voicemail "email" addy.
Clear as mud isn't it?
