While email and text support saw an increase in recent years, many customers, partners, and potential hires still prefer to call your company directly. When writing your voicemail script, include basic information such as a short greeting, your company name, an invitation to leave a short message, and the time frame in which the caller can expect a return call. If relevant, you may want to include your office hours, extensions for company departments, and the contact information for your office manager or HR department.
"Hello, you've reached [name] at [company]. I'm unable to come to the phone right now. Leave your name and number, and I'll return your call as soon as I'm free. Thank you."

Shared voicemail and call routing is intended for multiple access and directing calls to one or multiple phones. Mobile apps are also available that allow you to check your messages from your phone. The below infographic outlines the current state and trends of voicemails.
