A Short Essay On Multi Line Commercial Phone Systems And How They Work

October 3, 2011

While most commercial phone systems offer standardized features such as voice mail, call forwarding, transferring and hold music, not all are created equal. There are three different variations of these systems, but choosing the right one among the three is extremely important if you want to go for one that reflects the present and future plans of your business. For instance, you may opt for a KSU-less system if you run a company with only a few employees. Functionality is not sacrificed despite the very low cost you have to pay for KSU-less systems. KSU-less phones are not tied together in the sense that traditional phone systems are. In this type of commercial phone system, the handsets are not connected to one specific control unit, but have all the standard features of a commercial system.

For mid-sized companies, key systems offer more features and are expandable for normally up to 35 handsets. Key systems are naturally operated by something called the KSU, or key system unit, which is tasked to manage all outgoing and incoming calls as well as the entire network of phones in your business. While key systems still rank below PBX systems (see below), a lot of recent models are so advanced they can give PBX systems a run for their money.

Now the PBX system would be the most ideal option if you run a company with more than 35 to 40 employees. Not only are PBX systems very versatile, you can also expand them based on your needs. Because the PBX system is such a high-end phone system in itself, it can handle a large number of phones through its control terminal, much more than the similar key system can handle. Most PBX systems if not all come with standard features for large business requirements, so you need not worry about how your phone operations would turn out. You can program PBX systems to further cater to your personal requirements. The only downside to PBX systems is the overall expense compared to key systems and KSU-less systems. It’s PBX for bust if you are a business owner with over 35-40 employees, or planning to expand in the future.

There factors that will determine the size of the system you need are the number of lines and the number of extensions you will need. Lines are outside phone lines, but not any outside phone lines, as this defines the number of which that can be connected to at the same time. Extensions, on the other hand, are what a handset or similar device needs in order for your company to be connected to the phone system. Knowing both can give you an idea of which phone system is right for your business.
