Acronym for Direct Inward Dialing [DID] or Direct Dial-In [DDI]. The DID designates a specificity of the ISDN network (analog lines) which makes it possible to call directly an internal station (to a company, an administration) with an external telephone without intermediary. It is also called a direct number. By abuse of language, one calls DID all the telephone numbers.
