EXPLANATORY NOTE

AUG 22 P 5 :03 
Prank callers are, in a word, obnoxious. Thousands of people are bothered by one form of 
prank caller or another every day. Prank calls range from annoying hang-ups to false calls to 
emergency services or bomb threats. Some prank calls may even waste the time and resources of 
emergency services. Although prank calls may easily be traced through Caller ID, most 
telephone companies permit callers to withhold the identifying information from calls. 
This bill prohibits local teleccllminunications companies from offering services which 
, 
allow the blocking of information fro~ caller identification devices including per-call blocking 
and per-line blocking in order to identify the caller's identification number and minimize the 
I 
number of prank callers.'
