Writing a script doesn’t mean you have to write a speech. A simple greeting is fine, like this sample voicemail message:

3. Push the asterisk (*) or pound (#) key and then press the call button to call your voicemail. In some cases, you might not need to press the call button but you usually will have to listen to an automated greeting before you can hear your voicemail. Check to make sure that the asterisk or the pound keys are the correct buttons to press. Which key to press and when to push can depend on your cell phone provider. For most cell phone companies, it's often one of these buttons. Try both, and if neither of them work than visit the website of your phone company or call customer service.
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.
