Now days Business Phone Service come packed with a lot of features. You can basically customize your business phone service to fit your business needs. When you see the features, you will know how your current phone system is not good enough. I have been using hosted pbx from Telcan. With this business phone service, I can customize the welcome greeting, route calls to multiple numbers, even program what phone number to call at what time, have a professional voicemail, get my voicemail emailed and the list goes on. It is very easy to set up using wizard. Check out http://www.telcan.net/BusinessPhone/
