Now that you know which script to use, how do you record it? Depending on your budget and the resources available to you, you can record the script yourself, use a text-to-speech program, or hire a professional voice actor to record your greeting.
Professional business voicemail greetings are significantly different from ones you record for individual use and complete your professional business image. They’re more generic in nature and designed to provide information to the caller while ensuring they leave a message. Where possible, explain when you expect to return calls. Typically, they’re recorded for the following:

Consider for a moment how your phone is currently being answered. Professional courtesy is quite often not the standard for many college students. An abrupt "Yeah!" could be listed among the more courteous greetings. The more outrageous remarks will often buy you a major black mark in the professionalism category—even if it was your roommate answering your phone and acting crazy. A simple "This is ____" is always a pleasant change for a college student call. Make the change today, before the next (or first) employer phone call. If you have a landline, you should also encourage your roommate to do the same.
