If you are covered by common carrier legislation in your municipality, 
then yes, this is illegal, and you can be held liable for any damage you 
may cause by disclosing this information. (Woman calls home from shelter 
to talk to children, abusive husband finds out where she is, bad things 
ensue (this has really happened))

If you are not currently covered (presumably because the legislation 
hasn't caught up to VOIP providers being in existence), then you should 
still act as though you are covered, since you are purchasing wholesale 
service. If you are purchasing _retail_ service and your upstream 
carrier is not removing the blocked CLID/CNAM before it reaches your 
PRI, then they are in error and you should notify them immediately.
