There's no greeat trick to it.  Your provider just has to support it. 
My PRI provider here in the US allows me to set my CID, but it has to
fall exactly within certain parameters:  it has to be 9 digits and
within my DID block.  If it doesn't fit those parameters, the provider
will just blank out the caller ID.  As I understand it, the policies
of various providers vary greatly, and some providers won't allow you
to set CID at all.
