Learn about 4-line phone systems

Written by Steve Thompson
In the world of telecommunications, four-line phone systems are some of the most popular products. They are ideal for small businesses because they are not extraordinarily expensive and provide a wide range of flexibility as the small business begins to grow. If you are considering four-line telephone systems, it is important to understand exactly what you are buying.
Overview of Four-Line Phone Systems
When a telephone system has four lines (or "trunks"), this refers to the number of outside lines that can be routed through a particular phone or set of phones. For example, if your business has four employees, this type of system would allow each worker to have his or her own line.
However, four-line phone systems can also come with multiple extension capability. In other words, customers can call one number and dial an extension to reach multiple people on that same line. This can work for both individuals and departments. When buying phones, you will see the lines and extensions together with an "X" between them. For example, if a telephone can handle four lines and 16 extensions, it will be represented as "4 X 16."
Features and Pricing
Most four-line phone systems come with all the bells and whistles you would expect from business telephones. You can incorporate caller ID, voice response, call waiting, customized voice mail and a host of other features with the product.
Most of these phone systems are very inexpensive, ranging anywhere from $50 to $600 per unit. This makes them ideal for very small, start-up or fledgling businesses that do not have much disposable capital. Of course, you can always upgrade should you outgrow your current system.
Advantages and Disadvantages
Four-line telephone systems are ideal for businesses with very few employees or departments. Although you can increase the service range for these systems by using extensions, there is still a limit to what you can achieve.
However, the relatively small capacity of four-line phone systems makes them very limiting in terms of growth. It is important to consider the future of your business; even if your call volume will be more than satisfied now by four lines and a handful of extensions, you might need far more in the future.
Making a Purchase
With reasonable growth in mind, evaluate the features, prices and other considerations for several different phone systems before making a decision. For example, if you currently need only four lines with eight extensions, consider buying a phone with 12-extension capability just in case you need those extra extensions in the future.
