We just got an email from a large Tier1 carrier: Please be informed as a result of increasing fraudulent call scenario?s in the wholesale market, <CARRIER> will no longer be able to terminate traffic towards United States, effective June 15th 2020. The traffic will not be completed, hence you are advised to reroute your traffic. I wonder if this is the result of STIR/SHAKEN or something else.
