Give them a reason to call you back. In both voicemail messages, did you noticed how I mentioned new information they might be interested in? That will grab their attention more than simply introducing yourself, thanking them and asking them to give you a call if they have any questions. Come from a place of helpfulness by giving them something to look forward to and that will solve a problem.
“Hi, you’ve reached the desk of (your name). I’m currently out of the office on vacation and will return on (insert date). If you need immediate assistance, please call my assistant, (insert assistant name) at (insert assistant’s phone number). Otherwise, leave your name and number, and I’ll get back to you when I return.”

But to make them work, you need a business phone system that makes recording, tweaking, and uploading voicemail greetings simple. MightyCall provides such an answer for businesses. With simple, visually-based call flows, adapting your voicemail messages for different seasons, customers, and even different times of day demands no tech knowledge
d. Utilizing Ambiguity Over Clarity: When setting up your voicemail greeting be direct and to the point. Tell callers your information, a brief greeting, and direction—i.e. “Hi, this is Jim Shamalam (from Iron Industries). Sorry I can’t take your call right now. Please leave your name number, and a brief message and I’ll get back to you as soon as possible. Thank you.” This is ideal, as you inform callers and let them know what they should do to ensure a return call. A lack of direction can lead to callers leaving incomplete messages (lacking contact or other information) or even callers hanging up without leaving a message altogether.
