Check out STIR/SHAKEN: https://transnexus.com/whitepapers/understanding-stir-shaken/ https://transition.fcc.gov/cgb/Robocall-Strike-Force-Final-Report.pdf For what it's worth, American Express Fraud Department comes up at "Spam Risk" through my provider. There are "recommendations" for labels. I do believe the carrier is setting the labels and I would reasonably surmise they are the source. It could be prior use of an assigned number. Or not. I am not aware of how to get the labeling of a number fixed. Anyone? YMMV. Best, -M< On Thu, Oct 31, 2019 at 8:24 AM Ca By <cb.list6@gmail.com> wrote:

One of our customers office number is coming across as 'Survey Call' on T-Mobile cell phones. I know with certainty it's with 'T-Mobile' phones. I don't have another contact on another network that I know I can try. How do we get that fixed?
Thanks for any suggestions!
Probably number spoofing and has nothing to do with T-Mobile
