DID stands for Direct Inward Dialling, although the term DDI standing for Direct Dial In is used in the UK and some parts of Europe and Asia. A DID or DDI is in simple terms, a telephone number.

DID are purchased from one or more of the large wholesale DID providers and resold to customers. DID can be supplied from all over the world giving your customer commercial advantage of having local numbers in different parts of the world without the need to have a physical presence.

DID may be delivered via Voice over IP or via a TDM connection such as a T1 or E1. DID are then sold to customers, and forward to the customer either using VoIP or the public switched telephone network.
