Do they want to sit through an IVR menu that may or may not direct them to the right person? Do they know you’re a one-man/woman team and there’s no reason to sit through a menu? Skip the menu entirely and let them leave a message as quickly as possible. There’s no reason to add any additional steps or make your customers go through leaps and hurdles to leave a simple voicemail. When you identify what your customers’ pain points are, you make it much easier to determine what you want them to do to save everyone from the unnecessary stress.
Instead of leading with tired old lines like 'Your call is important to us', brush up on your telephone etiquette and start your voicemail with a thank you.

It’s also imperative for you to relay that message. If a client comes unprepared, you know your time is going to be wasted trying to work around a missing document. To avoid this, make sure your voicemail greeting emphasizes the importance of coming to a meeting prepared with any information that will speed up the process and make your life easier. Highlight some of the most common documents and pieces of information a client will need to bring, so they start off on the right footing.
