STAMFORD, Conn. – Charter Communications, Inc. today announced the launch of Call Guard, a feature for both Spectrum Voice® and Spectrum Business® Voice customers that automatically blocks malicious robocalls and sends caller ID alerts for other suspicious telemarketing calls.

“Robocalls are consistently the FCC’s most frequent consumer complaint and we understand these unwanted or fraudulent calls are not only a nuisance, but can also pose a security threat,” said Carl Leuschner, Spectrum’s Senior Vice President of Internet and Voice Products. “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.”

The FCC reports receiving more than 200,000 consumer complaints each year regarding unwanted calls and it has been estimated that U.S. consumers receive billions of robocalls each month.

How to Block Robocalls Using Call Guard

Call Guard monitors incoming calls and applies advanced analytics in order to appropriately score and categorize them. The scoring system helps differentiate between fraudulent calls and robocalls that are delivering important information from organizations like schools or health care providers. Malicious robocalls are automatically 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 Voice and Spectrum Business Voice customers.

Customers can access Call Guard through their voice portal at or in order to personalize their experience. 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.
