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.</div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Fri, Nov 1, 2024 at 2:21 PM Mike Hammett via VoiceOps <<a href="mailto:voiceops@voiceops.org" rel="noreferrer noreferrer" target="_blank">voiceops@voiceops.org</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">Sorry, you're right.<br>
