Ninja Number provides a virtual phone system for business owners to manage their communications and allow them to focus on more important aspects of their business and personal life. We’ve used leading-edge technology and artificial intelligence to create a mobile app that will save them time and money.
Your voicemail message should ideally answer all of the following requirements: Brief -- nothing bores callers as much (or makes them hang up as often) as long voicemail messages; Informative -- if it's your professional voicemail, say your name, business, and if necessary, department. Let your callers know when to expect a return call

Note: The primary phone number cannot be unassigned from the Auto Attendant. To release the main number, you need to swap it with another spare phone number on the account. Released numbers can be later assigned to a user, a Hunt Group, or any other object on the account. Toll-free numbers cannot be used as primary users' numbers.
If you have indicated you will be checking messages, ensure that you do so. If your ability to do so changes, remember to update your greeting. Tip: have someone else call your voicemail and check your greeting. You may not hear your own omissions.
