Zusammenfassung:Caller Name Identification, or CNAM Caller ID, is a telecommunication end-user feature that appeared for PSTN landline customers in the late 1980s. The rapid development of cellular mobile and VOIP telephony systems lead to the frequent omission of the CNAM Caller ID feature. Described is an independent end-user system that obtains the CNAM Caller ID after the call page transmission. The system operates on the user's smartphone or on a TCP/IP connected computer. A user with multiple telephone devices (i.e. a smartphone, landline, and VOIP line) may share use of this system between all devices.
