We have been going back and forth with our carriers about this for a while.  Both Lumen and ATT provided us with these links to lower the spam rating on specific DIDs.  We have had multiple successes with Hiya.

AT&T

Select \"Change or remove the caller ID information or Spam Rating of a number\"

In the description field you can describe the trouble and specify the phone number(s) that are being flagged as Spam and request that they remove the Spam Rating.

T-MOBILE

Here is a link that we found through the T-Mobile website to remove the Spam Rating.

Verizon Wireless:

Here is a link that we found through the Verizon website to remove the Spam Rating.

I wouldn’t be surprised if they were labeling based on the ‘crowd’ sourced data they get from the spam apps they have out there now.  There is a service you can pay to deal with this, but it is exorbitant in cost.  We have had those issues and found the price to fix this on carriers external to the ones we use to be too costly to deal with.

CNAME dips are done by the called party carrier. Nothing you can do to change that other than change the calling party ANI or work with the calling/called party carrier to correct the database entry.

I’m having the same issue with a couple of the TFNs as well.

What if you send TF number, instead of a DID?

Hello All,

An issue has come up again and I was hoping maybe someone here had delt with it and possibly had some advice. More and more, the DID numbers we send out as calling party number are being flagged as “Possible SPAM” or other types of “Probable SPAM” messages with the mobile phone carriers. As a result customers wont answer the call. These are legitimate customer calls and not any kind of cold calling or telemarketing. I took this up with Verizon and AT&T reps last year and got a lot of excuses and basically they told me there is no way to “whitelist” list numbers, the systems use some kind of AI processing to decide what calls to flag. So the issue has come up again because customers are requesting callback and when we call them back sometimes its flagged as possible SPAM so they don’t answer the call. Has anyone else found a way to deal with this? Hopefully once STIR/SHAKEN is fully implemented, they will stop doing this but until then its causing us quite a bit of headache.

Thanks
Jason
