Business phone systems are not useful and are incomplete if it cannot fully extend the telecommunication requirements of a business. Companies are adopting latest phone systems as a response to the growing business. Answering and making calls anywhere, within the business premise, is not the only application a business phone extension can offer. With the right technology, planning and utilization, a phone extension can put every department, employee and remote office in coherence with one another. Thus, making the business unified.

It is impractical to assign every employee his/her own private phone number. Aside from being messy, it is also costly. So instead, trunk lines can be used. This will allow every client and employee to share a set of lines, frequencies or extensions.

With this system, every telephone unit is assigned a specific extension number. So calling or referring to a specific phone is easier. An auto attendant can redirect a caller request with the use of an extension number and, for security reasons, extension to extension calls can also be made within the company.

Transferring of employees, on any office, room or department, is possible without losing his/her own personal extension number. Even a whole department can be easily relocated within the office building with ease.

Some telephones in a phone system extension can even offer intercom functionality as a portable means of using private and limited dialogue within the business.

Modern virtual PBX extensions added more flexibility with the use of softwares. Adding, removing, modifying and setting-up extensions can be done right from the desktop PC.
