Is a PBX system right for you? The easiest way to think of it is a multi-line system that allows inter-office communication by means of extensions. Each of the internal extensions all share a specific number of outgoing phone lines to communicate with customers or others outside of your office, private voice mails, and an interactive incoming call system.
One of the biggest benefits of installing a free open source PBX phone system for your business is that it can double as an extra employee when you need it. These systems have been continuously advanced over time for a more personal feel. They can warmly greet customers when they first call up and efficiently route them to the appropriate department.
