CID

    (CID) A short piece of text transmitted by
   some telephone systems describing the origin of a call,
   e.g. the name of the caller.  Some telephone handsets can
   display this.  A computer telephony integration system might
   use it to trigger actions on the callee's computer such as
   looking up the caller in a database and displaying their
   details on screen.

   There may also be a separate "caller id number" giving the
   telephone number of the originator of the call.
