If the office has several city lines, then the connection of the PBX will allow the most efficient use of telephone communication without the use of any special devices. Office PBXs are electronic devices that organize general communication within the institution with access to the city network. They can be either the simplest, with one incoming external and some number of internal lines, or full-fledged stations using digital technologies.
Office PBXs provide their users with a lot of additional service capabilities. This includes the optimization of external telephone lines, as with any outgoing call from the office to an external landline phone, the PBX independently searches for a free one. At the same time, telephone calls within the office are carried out in addition to the city lines.
Plus, putting a mini-PBX in the office simplifies internal operational communication between employees. After all, each of them gets the opportunity not only to phone with neighboring departments, but also to participate in a conference call, that is, it has the opportunity to communicate with several subscribers at the same time. Conferencing is possible even if one of the subscribers is out of the office.
Additional amenities include internal and external paging. The first allows you to submit information through the external speakers on the entire territory. External communication provides an opportunity to receive timely information about events occurring in the institution, such as equipment breakdown or unauthorized entry into the office.
Do not forget about the functions of a PBX, such as call forwarding, automatic number identification, recording a telephone conversation, voice mail. It is even possible to connect an intercom to the telephone and open the door to visitors by pressing a button on the telephone.
