An insurance agency reports that AT&T's network is flagging their brand new, legitimately used phone numbers as "Spam Risk" after only about three calls, despite valid A-level STIR/SHAKEN attestation.

Most carriers and SPAM reputation companies factor this into the equation.\n\n Surprisingly, this is public info and there are OpenAPIs that can be used to look the porting status.\n\n Edited to add: I know you know about the LERG. Was explaining it for others. 😉",

Trying to understand a tagging problem that per-number behavior doesn't explain.\n\nSetup: We buy pools of local DIDs through a wholesale provider that handles STIR/SHAKEN signing. Each rep gets a pool and we rotate. Per-number volume is roughly 30 dials/day, about 150/week. The provider says these DIDs sat unused in storage 12+ months before assignment.\n\nProblem: Brand new numbers show \"Spam Risk\" on AT&T within about three dials. Three calls cannot build a reputation on their own, so something upstream of per-number history is driving it.\n\nWhat I've ruled out using SIP traces:\n\nSignature is valid and the signed orig.tn matches the caller ID actually presented. Attestation A.\n\nNo internal routing identifiers of ours leak into the outbound INVITE. Verified by full-message search.\n\nSo this isn't a signature/caller-ID mismatch and it isn't attestation level.\n\nWhat I found in the LERG: I resolved every thousand-block in our pool to its carrier. 71% trace back to a single wholesale CLEC, spread across ~28 state-level entities. The two numbers that flagged together in my test sit in the same thousand-block.\n\nWorth noting for anyone doing this analysis: different thousand-blocks inside the same NPA-NXX belong to different carriers. One prefix in our pool splits across four separate carriers by block. Prefix-level lookups gave...",
