A general voicemail greeting is what callers will be greeted with if you are unable to answer the phone at work. It is the everyday greeting, used as the default, unless you have set up a temporary greeting, such as an away message while you're on vacation, or a special message during a holiday.
Hi, this is [Name]. I’m not currently available at the moment, but I look forward to talking with you. Please leave your contact information, along with a short message, and I’ll make certain to return your call.

Your voicemail needs to have relevant information such as your name, who the prospects are connecting to, the department you work in, why your not available to assist your prospects, when you will call them and related information, this is what the prospects would prefer hearing instead of dragging the voicemail messages speaking about your brand and more.
Why your business voicemail greeting matters A good first impression goes a long way, and a voicemail greeting is the first impression to your business. An expertly crafted voicemail script lets your clients know you’re dependable, capable, and confident. An unprofessional voicemail script, on the other hand, can do the exact opposite.
