What is a DID?
DID stands for Direct Inward Dialing, also known as DDI Direct Dialing Inward in Europe. It is a feature offered by carriers or the telephone companies for usage with their customer’s PBX (Private Branch Exchange) system. Carriers assign a variety of phone numbers related with one or more phone lines. Then, DID allows you to allocate a personal number to each employee without the need for a physical phone line to connect to the PBX. This way, call traffic can be split up and managed more easily. Callers who have a direct number can bypass the auto attendant and directly reach their contact via a direct extension. This also makes telephone service more cost-effective for your business.
