what are different functions of PBX devices?

Organizations are using PBX devices to connect their all internal telephones to an exterior line. With the help of PBX, they are able to use only one phone line for many people, each one having separate telephone at their desk with different number inside the organization. However, the number is not in the same format as a usual phone number because it depends on the inside numbering. While using PBX device, you need to dial only 3 or 4 digits to make call to another phone inside the same network in the organization. We often call this number an extension and each desk has its unique extension. An individual calling from the outside the company may ask for an extension to be routed to the person he/she is seeking for.
