I finally got a number! It's suburban Chicago Sprint (now T-Mobile). I guess that kind of throws the rural carrier idea out the window. Apparently a non-zero number of people are expecting caller ID name to work on their mobile devices, but there are clearly caveats to that. ----- Mike Hammett Intelligent Computing Solutions http://www.ics-il.com Midwest Internet Exchange http://www.midwest-ix.com ----- Original Message ----- From: "Mike Hammett" <voiceops at ics-il.net> To: "VoiceOps" <voiceops at voiceops.org> Sent: Thursday, April 22, 2021 4:01:02 PM Subject: [VoiceOps] Malformed Caller ID Have any of you noticed an increase in customer complaints of malformed caller ID? We do a test call out as the customer, whether it's to one of our cell phones or one of the incumbent's POTS lines. Everything shows up as expected. The number is formatted correctly. The Caller ID name is formatted correctly. However, we're getting customer complaints that the caller ID is saying Japan (we have nothing to do with Japan), United States, blank, or some other combination. We're just not able to confirm that. Of course customers are reluctant to tell us what the numbers are of the remote parties having these issues, so we can't really look for common denominators. ----- Mike Hammett Intelligent Computing Solutions http://www.ics-il.com Midwest Internet Exchange http://www.midwest-ix.com _______________________________________________ VoiceOps mailing list VoiceOps at voiceops.org https://puck.nether.net/mailman/listinfo/voiceops
