Tough question... likely only for Android freeware experts... 

How does incoming caller ID work and more specifically 
is there a method you know of to CONTROL its source data?

Essentially, the goal is to shift incoming CallerID off of the 
system internal default contacts sqlite database onto a 
given privacy-oriented contacts database of your own choosing.
