I set caller ID to a unique identifier before sending to a transfer 
partner or overflow call center.  This makes it much easier to match 
CDRs and get stats on the outcome of calls once they leave our center.  
It is a very valuable and legitimate use.  Am I committing a crime?  nah.

We use and trust ANI, not caller ID although I think I read you can 
manipulate ANI if you have an SS7 link.  I have yet to play with SS7.
