Charter Expands Reach of Robocall Blocker

Charter Communications said it now offers Nomorobo, an app that blocks unwanted telemarketing and robocalls, in its legacy systems. The app was already available to customers in the former Time Warner Cable systems that Charter acquired in May 2016.

Nomorobo auto-blocks automated calls from telemarketers using a list of known unwanted phone numbers, including those on the “Do Not Call” Registry. The call rings both the customer’s home line and the Nomorobo platform simultaneously. If Nomorobo recognizes the call is from an unwanted number, it will be blocked.

Nomorobo does allow certain automated calls to get through, including school closings, doctor’s appointment reminders, tornado warnings and prescription pickup alerts.

Charter said Spectrum Voice cutomers can activate the Nomorobo feature by following instructions posted at

In a July blog post, FCC chairman Tom Wheeler noted that robocalls and telemarketing calls are currently the number one source of consumer complaints at the Commission, adding that he had sent letters to the CEOs of major wireless and wireline phone companies calling on them to offer call-blocking services to their customers as soon as possible, and at no added cost.

“Customers now have even more control over the calls that come into their homes,” Rich DiGeronimo, Charter’s EVP of products and strategy, said in a release. “Nomorobo is one of the many ways we continue to enhance customers’ home phone experience with unmatched reliability and service in addition to a wide range of popular advanced phone features available at no extra cost.”
