Unfortunately, you're at the mercy of the call-ed party's carrier.  A lot
of providers maintain their own database, and only periodically update it.
I suspect this is a hold-over from when dips were expensive.  That carrier
may, or may not update their databases regularly.  For esample when I call
one of our consultants, my caller id comes up on his phone as the person
who had my DID 20+ years ago, well before we had a relationship with the
consultant.  The correct information is being sent from our switch, and
Neustar has the correct information, but his provider (I think verizon) is
sending something that's completely wrong.
