With Nomorobo, you can block unwanted calls from telemarketers and robo-callers. This feature uses a list of phone numbers from the FCC Do Not Call list to block suspected calls. This service is available for your landline Spectrum phones at no additional charge.

To activate:

  1. Go to the Nomorobo website and follow the directions to sign up.
  2. Sign in to Spectrum.net and go to your Voice Online Manager to activate the Simultaneous Ring feature.

This feature will screen all incoming calls. If Nomorobo determines that the call is from a blacklisted number, it will block it. In this case, you'll hear a single ring. The number will show up on your caller ID on your handset and television, if applicable.

Note: After you activate the Nomorobo feature on your phone line, you will no longer be able to access Spectrum Voicemail by dialing your home phone number. You'll need to dial *99 from your home phone to access your Spectrum Voicemail.
