Interested in a Vonage® business phone system?

Phone spam checked on all incoming calls, and instant warnings on your caller ID.


For your busy workforce, phone spam and telemarketing calls not only represent an annoyance—but they often result in lost productivity that can harm your bottom line. The good news is that Vonage Business customers can employ our Spam Shield product to detect and warn users in real time of unwanted phone spam before picking up the phone. The product also benefits your mobile teams who take incoming calls on the Vonage mobile app or desktop app.


When you activate Spam Shield, the phone number of every incoming call is immediately run against a dynamic database of numbers associated with telemarketing, robocalls and scams. When the caller’s number is matched to this list, that number and a “Suspected Spam” notice is shown on your caller ID—allowing you to decline answering the call.*

Another benefit of this service is that all spam-associated numbers are flagged. So, you can add them to a block list and never experience calls from these numbers again. That means fewer calls you don’t want and less time spent dealing with them.

*Accuracy of spam identification may vary.


  • Avoid annoying spam calls that inhibit day-to-day productivity.
  • Automatically get “Suspected Spam” warnings on your desk phone, smartphone caller ID, and computer desktop.
  • Add all detected spam-associated numbers to a call block list, and cut down on unwanted calls in the future.
  • Ideal for individual employee extensions and call center extensions.
  • No configuration is required. The service works upon activation.


Spam Shield is a premium feature that can be easily added to any extension on your Vonage® Business Cloud account. Add the feature yourself via your admin portal or with the assistance of a Customer Service representative. Once activated, no configuration is required.
