Charter adds robocall blocking feature to Spectrum services

Charter Communications has launched a feature for business and individual customers of its Spectrum telephone services that blocks robocalls and sends caller identification alerts for suspicious telemarketing calls.

“We are making Call Guard automatically available to all our customers as part of our commitment to providing quality products that prioritize safety and security,” said Carl Leuschner, senior vice president of internet and voice products for Spectrum.

Leuschner said robocalls not only rank among the most frequent consumer complaints to the Federal Communications Commission, but also constitute a nuisance and even a security threat.

The FCC reports more than 200,000 consumer complaints each year regarding unwanted calls. By one estimate, U.S. consumers receive billions of robocalls each month.

 Call Guard monitors incoming calls and applies analytics to score and categorize them. The scoring system differentiates between fraudulent calls and robocalls that deliver important information from organizations like schools or health care providers. Malicious robocalls are blocked, while suspicious telemarketing and spam calls are delivered with a caller ID alert, notifying customers of a spam risk.

Call Guard will be automatically activated and provided at no additional charge to Spectrum Business Voice and Spectrum Voice customers.

 Customers can access Call Guard through their voice portal at or to personalize their experiences. Through their voice portal, customers have the ability to view which numbers have been blocked, add additional blocked numbers, add allowed numbers to ensure important calls are delivered or turn off the Call Guard feature.
