Industry Update: Call Blocking and Whitelisting Links

WHAT’S HAPPENING? CARRIERS HAVE BEGUN TO BLOCK OUTBOUND CALLS IF THEY APPEAR UNWANTED OR FRAUDULENT

In an effort to protect consumers against abusive robocalls, carriers are increasingly implementing call blocking programs.

In recent weeks, Vartel has observed AT&T, Verizon and T-Mobile increasingly blocking calls that they feel fit typical robocalling campaign characteristics such as high-volume, short-duration calls originating from a single number. When implemented, a common effect of these call blocks will be a BUSY signal.

WHAT DO I NEED TO DO? PROACTIVELY REQUEST WHITELISTING OF LEGITIMATE OUTBOUND CALLING USE CASES

There are many legitimate use cases for high-volume, short-duration calls including school closing notifications, weather alerts, and patient reminders. These are entirely valid and legitimate use cases where recipients want to receive these calls and have opted-in to receive these calls; however, when viewed en-masse at the network level, they can look like illegal robocalling.

In order to ensure your outbound calls are not miscategorized as unwanted or fraudulent calls by the wireless carriers, we highly encourage you to proactively request whitelisting of legitimate outbound calling use cases from each of the major wireless carriers.

Below are websites where you can submit whitelisting requests:
