Ooma Office is the simplest to use, easiest to set up, and most reliable business phone system to help your small startup sound like a big business. There are never any contracts, and no scaling prices that increase if you need more features or more user accounts; it’s always $19.95/mo/user regardless if you have 1 or 1000 phone lines. Some of the features you get are a virtual receptionist call directory, call forwarding to your cell phone, free toll free number, and much more!
