The choice of a business phone system mainly depends on the size of the organization, and the number of extensions required. In recent years, the best business phone systems have become an absolute necessity in every establishment.
At present, there are mainly four major types of business phone systems in the market. This includes key systems, Private Branch Exchange (PBX) systems, KSU-less phones and Voice-Over-Internet Protocol (VoIP). Each business phone system comes with different features and can accommodate different number of stations to meet individual needs.
Key phone systems are mainly controlled by a device called the key system unit (KSU). This business phone system comes with features that are not available in ordinary phones. Key phone system allows the user to make calls to another in-office extension, and permits only one user to hold the line. Key phone systems can support five to forty extensions. Therefore, they are the best business phone systems for small and medium sized business organizations. The cost of key systems fluctuates between $350 and $1000 per user, and mainly depends on the features.
If the demand is for advance functionality and more than 40 extensions, then private branch exchange (PBX) systems will be the best business phone system. The early model of private branch exchange systems was huge. With the advance of technology, private branch exchange systems have reached a point where they can be placed on a desk, and include all the standard features. Some private branch exchange systems can also be totally programmed. The cost of a large private branch exchange system is approximately $800 to $1000 per user. Hence, private branch exchange systems are ideal for large business establishments and for medium business establishments with more than 100 employees.
KSU-less phone systems can accommodate a maximum of 10 extensions. This type of system is not permanently wired into an office, but can be moved from one place to another. Some KSU-less phone systems also come with features found on key and PBX systems. Therefore, KSU-less phone systems are the best business phone systems for small offices with fewer people. A KSU-less phone system would cost around $130 to $225 per phone. As it is inexpensive, it is not generally sold or supported by telecom vendors. This means that you have to do the shopping, installation, programming and maintenance of KSU-less phone systems yourself.
The Voice over Internet Protocol (VoIP) is one of the latest ventures in the business phone system. VoIP is a common term used for packet-switched connection to transmit voice, fax and other forms of information. Today, this new telecom technology is equally accepted by small, medium and big business organizations.
