Remember, you need real-world situations to prepare for the sales game. Roleplay with colleagues and friends to get honest feedback on your voicemails.
Company-level calls are usually directed to your general business number. There are occasions when everyone in the office is tied up and unable to pick up calls. It’s important to gather information about the reason for the call so that the right person or team can call them back. These greetings ensure that customers do not feel neglected while also providing assurance that their call will be attended to as soon as possible.

To end the voicemail, state (or restate) your main question, then say your phone number. You can also say you’ll follow-up with an email. Now, this isn’t the same as saying, “If I don’t hear from you, you’ll hear from me!” Instead, it’s giving them another way to contact you, one they may be more comfortable with. They should still feel a responsibility to respond to your question, but now they have two options for how to get back in touch. (Then send that email, of course.)
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.
