My invention is a call processing circuit built inside a phone or connected to the phone through its I/O interface for uniquely defining/forwarding abbreviated phone numbers over one or several phone-area codes in conjunction with a telephone-computer integration system at an agent station whose phone number is pre-set in the call processing circuit and is automatically dialled if the dialled digits starts with a special ring digit (e.g.; #, *, #*, or *#). The call processing circuit also has unique hardware ID code to be retrieved automatically by called party (without any caller's effort nor any telephony centre involvement) for being used as an alternative non-phone number based Caller ID.
