Call a service for messages, and never use the phone while driving. It is not only dangerous, but what you say while distracted may require more explanation later and rob you of time. If needed, pull over and call from a parked car. Check to see if another application that you already know is compatible or a useful substitute. Schedule your viewing time.
Tape record any special events.
Make it clear that the caller must leave a message or the page cannot be returned. This way you can screen extraneous calls. Do not stockpile old technology items. Turn off during nonworking hours. Enroll in a No Junk Mail system.
