The ISDN calling line identity (CLI)
The ISDN caller ID
—
also known as CLI (
C

L

dentity)
—
this is the telephone number
of the caller which is transmitted to the participant receiving the call. As a rule, it consists of
the country and area codes and an MSN.
The CLI is well-suited for authentication purposes for two reasons: it is very difficult to manip-
ulate, and the number is transferred free of charge via the ISDN control channel (D-channel).
