at the same time and sometimes the phone lines go dead.

   (or press '2' to listen to the message) 
3. Punch in the phone number (incl. area code) of
    whom you wish to contact.
4. Listen to the guidance, then press 1#.

    after the beep.  (message can be recorded up to 30 seconds)
5. Hang up the phone.
