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.<o:p></o:p></span></p>
