First you need to know how much time your phone system or provider allows for the duration of the greeting. Some are 30 sec some are longer. Then you need to have a few ideas of what you want to say, or ask your callers.
“Hi, you know who you called; leave a message, maybe they’ll call you back. Then again, maybe they won’t. That’s how life is. Point is, you’ve done what you can. Have a nice day.”

2. Professional voicemail greetings for your business cell phone number. It’s a good practice for each of your team members to have their own personal business phone numbers.
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.
