Answer: Your “Robo-Blocker” message is the message that is played to all callers unless they are on your white list.
You can update this at any time by uploading a .wav file on the Customer Portal under “My Numbers”.
Your “Unavailable” message is essentially your Voicemail message. If you do not pick-up the phone and the call times out, the caller will hear this message, and then have the ability to leave you a voicemail.
You can update the unavailable message by dialing your number from any external phone and pressing *8 once you hear your Robo-Blocker message start to play. Enter in your voicemail pin and then press 0, then press 1 and follow the voice prompt.
If you have a phone connected to a Cisco PAP2T, you can just pickup the phone and dial *97, then press 0, and then press 1 and follow the voice prompt.
