Although it is okay to give a little bit of information, keep in mind the goal of your voicemail is to take the next steps in the conversation, and not to have the whole conversation then and there in your recording.
Nobody wants to listen to a long-winded voicemail. Keep your greeting short, simple, and concise. A voicemail message should pique a client’s interest and leave them looking forward to your call. Stick to the basics, explaining your company name, hours of operation, and when to expect a callback.

Think through what you are going to say before you place the call. When men hear the beep, they often freeze up and forget what they wanted to say. If you want to be the go-to guy at work, then you have to exhibit competence on all levels. Don’t spoil your confident image by hemming and hawing and filling your messages with “uhhhhs,” and “ummmms.” If it’s a really important call, consider writing out what you want to say beforehand. If the person picks up, great, you now have some notes to remember what you wanted to talk about. If they don’t answer, you can leave a clear and concise message.
