The four main types of business telephone systems (key telephone systems, private branch exchange telephone systems (PBX), KSU-less telephone systems and voice over internet protocol) all provide the same basic function (i.e. to make and receive telephone calls), but there are significant differences between them. If you need a telephone system for your business, then it is worthwhile learning about each of the systems available to ensure that you get the one that is best suited to your particular circumstances.

Private Branch Exchange Telephone Systems (PBX) – This is the most expensive type of telephone system available but that is because it is also the most advanced one. It can deal with over fifty extensions and can be customized and upgraded as needed. If your company has lots of employees who require access to a phone, then this is the best choice for you. You will save yourself a lot of the hassle involved that comes with having multiple other types of telephone systems in use.

Key Telephone Systems – This is a good choice for small businesses who have between ten and fifty employees. However, even if you have less than ten employees, you should still consider this telephone system because it is cost-effective and easy to install / maintain. It is not difficult to expand this system (it can also be combined with a PBX system) if needs be too.

Voice Over Internet Protocol (VOIP) – This telephone system works over the Internet. You basically connect your phone directly into your computer. Features include number portability, voicemail and call waiting with caller ID. It is perfect for small businesses with limited numbers of employees but is impractical for larger businesses.

KSU-Less Telephone Systems – This telephone system is suitable for businesses with ten or fewer employees. It is cost-effective, easy to install and not difficult to move from office to another if you have to relocate. Another benefit is that it is highly customizable, so you can have it set-up in pretty much any way that you choose. The disadvantage of this system is that it if you need to upgrade it is quite expensive to do.

Ultimately, which telephone system you use is less down to personal preference and more down to the size of your business and how much you expect it to grow over the next few years. If you are not sure which one to opt for then speaking to a consultant at a firm that specializes in these systems is advisable.
