Some voicemail greetings are too loud and distracting and some are so quiet you can barely figure out who you’ve called. Whoever sets up the voicemail greeting for a business should be a confident speaker. Here’s a pro tip—write out a script of what the voicemail greeting should say and practice it a few times before you record it. It will be well worth it in the end!
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.

Doing this gives your prospects the assurity that you will follow up with them which makes them drop in their contact details for you to reach out to them.
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.
