An extension in a PBX is an internal destination to which a call can be routed: an employee, a department, a mobile or an app. In a cloud PBX an extension does not have to be a device in the office; it can be a mobile, a computer or an IP device.
What can you do with extensions?
- An extension for every employee with a short number, so transferring an internal call is easy.
- The mobile as an extension: answer the business line from anywhere without handing out your personal number.
- A group of extensions: rings several people until someone answers.
- A voicemail box per extension with sending to email.
- Adding and removing in minutes through the management interface, with no technician.
Extensions and the call router
The extensions are the destinations, and the call router decides which extension each call reaches, by hours or the caller's choice. That prevents lost calls.
