You can think of this process as the editing step before publishing an article.

As a rule of thumb, don’t use any voicemail that you think is subpar.
Once you thank your customers for calling, state your name and the department. Make sure to speak clearly so the caller knows they called the right place and can understand what is being said. Don’t rush through in case the caller wants to write the information down.

Most VoIP solutions will require stable and consistent internet connectivity at all your office locations where VoIP will be used. At the very least, your business phone system must have access to a business-class internet link, so discuss these needs with your company's internet service provider (ISP). This should be a dedicated link through a dedicated router if you expect your phone calls to sound as if they were coming from a business and not someone's home Skype connection. At a minimum, it's important to have a router that can create virtual LANs (VLANs) and also has the ability to encrypt your voice traffic. These days, you need end-to-end VoIP security for any call.
