    In his otherwise very erudite treatise on incoming call ID Larry
Lippman @ Recognition Research Corp makes this categorical statements:

"	Not only that, but even in the most sophisticated ESS central offices
if the call originated in ANY OTHER CO, the destination CO has NO information
anywhere in its processor as to the identity of the calling party other than on
what interoffice trunk the call came in on. 
	There is no possible motivation for an operating telephone company to
install apparatus in its CO to make calling party identification available to
subscribers - even if the information were available. "

    I suggest the research by Recognition Research into the following might
be of some value!:

         1.  ISDN
         2.  CCITT Signalling Scheme # 7
         3.  The Field Trial of CCITT#7 in Orlando FL
