It entirely depends on how that carrier deals with caller ID. Usually you 
would not be able to set your own, as it's done by their equipment. It would 
just ignore yours.

The fact that you sometimes can, they would probably consider a flaw.

Being this is usually only handed over to them by other TELCOs, it's pretty 
much a new issue, and not something they are really prepared for.

In other words, they often have resellers. Smaller TELCOs which buy from them 
and resell to their customers. So that smaller TELCO would hand over the CID 
to the bigger carrier. They would also have a working CID system and the 
final end user would never be expected to be in a position to modify it.

Everything could start falling to pieces if that does not work as all the 
billing is based on identifying who is calling whom.
