Telnyx - How to Handle Spam Likely
Steps to follow to mitigate a "Spam Likely" flag on your phone number
If your phone number has been flagged as "Spam Likely" then:
Register your phone number with the FCR at https://www.freecallerregistry.com/fcr/.
Add CNAM by going to Mission Control Portal into the "My Numbers" section, find the "spam likely" phone number and click the cog icon for advanced settings. Once in the advanced settings you can enable CNAM Listing and add a custom name. CNAM is not applicable for toll-free numbers. Having CNAM information is important to the engines that analyze and identify phone numbers as "spam likely".
Image description: in advanced setting within my numbers there is a radio button you can toggle on so that you can add CNAM information into the custom name field.
Be patient, start to make calls, and wait for numbers to be aged. Time for aging can vary by carrier depending on which carrier is marking the number as "spam likely". There is currently not a rule of thumb for aging length for "spam likely" numbers but 1 week of healthy calls has been enough in certain cases in the past for a number to heal its "spam likely" status. Making unsolicited calls is how numbers get flagged as "spam likely" to begin with.
Lastly, you can push to the specific carrier that is flagging your calls. This page has a very complete set of contact information or forms to submit to each different terminating carrier:
US Carrier Call Blocking
Telnyx has become aware that major carriers in the US industry are actively flagging/blocking calls to their subscribers devices due to them deeming the calls as potentially fraudulent, where end users may see "Fraud Risk", "Spam Risk", "Potential Spam", "Robocaller", "Scam Likely" and other names which their carriers are prepending onto your caller IDs.
We are seeing, that high volume calls from non-rotated caller IDs are experiencing a higher amount of user busy responses in the form of a SIP 480/486 Busy Here.
In some cases, it's also being reported that the carriers of the destinations are using services that are categorizing calls as "Potential Spam" on the user's devices.
What to do
We also understand that there are many valid & legitimate use cases, where there is a necessity for high volume calls (e.g. alerts, appointment reminders, etc.) Providers and their analytics partners have established mechanisms for callers to seek redress to fix any inadvertent call labeling or blocking concerns, as well as to register their numbers in the first instance.
The first step is to register with the Free Caller Registry. Several carriers use that to pull company information for phone numbers so having your numbers registered here will help lower the chances of terminating carriers flagging your numbers for spam.
Next step is to push to the specific carrier that is flagging your calls. This page has a very complete set of contact information or forms to submit to each different terminating carrier.
We are committed to combating spoofing and illegal robocalling through implementing the industry-wide STIR/SHAKEN solution, in an effort to play our part in reducing these illegal occurrences. You can read more about our three-part articles where we discuss the implementation in detail.
