Users often don’t invest enough time into their messages, resulting in incomplete, unprofessional, or otherwise under-whelming greetings. Sure, crafting a greeting doesn’t sound all that complicated; however, there are a number of pitfalls users can fall into—i.e. informality, terseness, sincerity, lack of direction, and more. While none of these sound too catastrophic, they are often interrelated. As such, they tend to worsen any problem. For example, humor can cause informality, worsen ambiguity, and weaken sincerity. That being said, users should strive to avoid ALL these pitfalls.
1. Actually Write a Script! Whether you are a solo therapist recording a voicemail greeting, or you have a whole office and need a system message, don't just wing it! Take the time to actually write out a script. Read it aloud to colleagues to make sure it says what you need it to say.

3. Be mindful of your voicemail message. You need to confirm they've reached the right place, that the message will be confidential (make sure it is) and what you want them to do next.
Voice mail on a cell phone works similarly to a message machine for a land line, as callers are able to leave voice messages in an in-box for the recipient to listen to at a later time.
