I wonder since when cel phone companies make $$ per call.
With CALLER ID, a name is displayed after the first telephone ring. Every call to a U.S. telephone number that has Caller ID enabled requires that the terminating phone company perform a lookup in one of several national databases. These are known as "line information databases" or LIDB. These databases contain all the U.S. subscriber names and numbers. This database lookup is called a "CNAM dip". When this database is being "dipped", the originating local phone company gets compensated by the terminating phone company – this is commonly referred to as a "CNAM dip fee". This compensation happens for every call where the calling party name is displayed to the called party – even if the call is not answered.I wonder since when cel phone companies make $$ per call.
