Hi all,
I  want to know how the CALL ID system works too? (TELEPHONE CALLER
IDENTIFICATION SYSTEM) This system is implemented in the US ROBOTICS MODEMS
SPORTER Vi Series.
I want to build this with pics 16C84 or others depending of software
requeriments or algorithm complexity.
Other topic of my interest is :
Somebody have specifications for 16KHZ TELEPHONE TAXATION SYSTEM ?
Please point to  WWW Site for ISO specifications !!!
Circuits schematics or software algorithm on this topics are welcomed...

Thank in advances
