Mitigating Spam Likely

Legitimate calls being marked as Spam is one of the most difficult problems that the telecom industry is facing right now.

Analytics engines can be very aggressive when it comes to marking DIDs as Spam Likely, and the tag can be applied after making only a few outbound phone calls. This can cause any number of issues for legitimate businesses that are simply trying to make outbound calls to their clients.

The purpose of this article is to explain how this issue occurs, and what you can do to mitigate the problem.

What variables are considered when a number is marked as Spam Likely?

While the metrics that are monitored can vary from carrier to carrier, these appear to be the common variables weighed against DIDs that are marked as Spam:

  • Quantity of outbound phone calls
  • Quantity of calls sent to VM
  • CPS (Calls Per Second)
  • Level of Attestation
  • Average Length of Call
  • Quantity of calls 6 seconds or less

What is the best way to mitigate Spam Likely Tags?

The best way to mitigate Spam Likely tags is to have you or your customer register their numbers with

This free portal streamlines the caller registration process with First Orion, Hiya, and TNS and registers the calling business with the Analytics Engines that support major wireless and wireline carriers in the US.

While this step reduces the likelihood of Spam Likely Tags, it doesn’t completely prevent it from happening. Outbound callers that produce high volumes of short duration attempts will likely still see the Spam tag applied to their numbers.

Note – This process is not a replacement for outbound Caller ID registration.

When should my customers register with the Free Caller Registry?

VI recommends that customers register their DIDs as soon as they are purchased. If you are porting numbers to your network, we recommend that you add registration with this database to your porting workflow after submitting the order to VI.

My Number have already been tagged as Spam Likely, what should I do?

If your numbers have already been tagged as Spam, we recommend opening a help desk ticket with the carrier that has applied it. Help Desk links for T-Mobile, Verizon, and AT&T are included below.




Are there any other ways to mitigate Spam Likely Tags?

There are a few other steps that you can take to mitigate Spam tags:

  • Ask customers to save your business number

Some third-party scam blocking apps allow users to block calls from unknown numbers that aren’t listed in their contacts, so your call may not reach them at all if one of those services are in use.

If customers are saving your number in their contacts, this will reduce the chance of that happening, while also making them more likely to ignore any spam likely tags since they will recognize your number.

  • Ask clients to adjust or remove third-party spam blockers

While this solution may seem impractical, it could alert your customers to potential problems they have with other blocked calls. Some users often have spam blockers installed unknowingly.
