If you run a private business or if you run a your business from home you should separate you private and business phone number. You will have the following benefits:
- Easy separation of business and private phones
- Proper end of business day, where you switch on voice box
- You can be more professional on answering your business phone
- More quality time on private matters since you take care of them when you really have time
Separating both phone numbers technically should not be an issue. If you are not sure on how to best realize it discuss it with your telecommunications carrier.
