Callers are customers of foreign operators who after dialing the access number communicate with the living operator or with IVR to identify themselves, usually by means of the card number issued by their operator. The call is then connected and charged to this card, or billed to the called party if accepts it (similar to Collect Call). HCD is operated according to the ITU Recommendation E.153.
