We’re all familiar with this type of voicemail greeting. Simply put, a caller reaches you by dialing your number or extension directly. For an optimal personal voicemail greeting, be clear about who you are, the team you’re on, and when the caller can expect a callback. Unlike company and department voicemail greetings, you may not be able to configure a greeting for open and closed business hours. If that’s the case, use a general voicemail greeting that accommodates both scenarios.
Voicemail will give you a brief description of the three steps involved in setting up your mailbox - setting a passcode, recording a greeting for your callers and recording your name. "Enter digits for your passcode." Your security code may not be less than four digits and no more than fifteen digits. For security purposes the system will not accept codes which are consecutive, sequential or your extension. Voicemail will repeat your passcode to you. Remember to keep this passcode secret and to change it regularly. (We recommend monthly.) "Press D" (the 3 key on your dial pad) to discard your greeting and record it again. When you are satisfied with your greeting and have pressed "X" (the 9 key on your dial pad) to save it, you will hear... "Recording complete." Next, you will record your name so that you and your callers hear your name in your voice. When Voicemail says, "Press D" (the 3 key on your dial pad) to discard your name and record it again. Voicemail will close out your session by reviewing your name and passcode. You are now ready to begin using your new Voicemail. ALWAYS PRESS X (the 9 key on your dial pad) TO EXIT THE SYSTEM BEFORE YOU HANG UP!! Questions or problems with voice mail can be directed to JMU Telecommunications at 568.6471.

There is no definitive answer here, but you should include one of the two at the beginning of your message based on what makes the most sense.
It's easy to get carried away in a voicemail and include more detail than is necessary. We've all been in that situation where the automated or pre-recorded voice on the end of the line goes on and on with more information than you can take in.
