When choosing a phone system, small business owners have traditionally had to settle for less when it comes to features and capabilities. Things like ACD (Automatic Call Distribution, or “holding for the next available agent), PRI (digital dialtone) support, Service Observe (ability to monitor staff calls for quality assurance or training), and more have been out of reach of many small businesses, because manufacturers tend to develop these types of capabilities for larger (and more costly) systems. This is true no longer with the arrival of the ESI-50, a truly capable small business phone system.
