An extension phone refers to a device that is an additional telephone connected to the main telephone line in a telecommunications system. It is also commonly known as an "extension" or "extension line." It allows users to have multiple telephones located in different parts of a building or premises, all connected to the same telephone line.
Typically, an extension phone is connected to a central base unit or main telephone set. The base unit is directly connected to the telephone line, while the extension phone is connected to the base unit through a physical wired connection or wirelessly through technologies like DECT or Bluetooth.
Extension phones are commonly used in homes, offices, businesses, hotels, and other settings where multiple phones are required for convenience and accessibility. They allow users to answer or make calls from various locations without having to move around the main telephone set. Extension phones often have similar functions and features as the main phone, including dialing, call answering, voice mail, call transfer, and call hold.
Moreover, extension phones may also have additional capabilities depending on the model, such as speakerphone functionality, caller identification, speed dialing, and programmable buttons for quick access to frequently dialed numbers. They offer practicality and flexibility, enabling multiple users to communicate effectively and efficiently within a shared telephone system.
