Block Telemarketing and Robocalls.


Optimum Voice customers can use Nomorobo, a free, independent call blocking service that answers known robocalls and telemarketing calls to your home phone if they are not already blocked by Block All Anonymous Calls or Block Selected Callers features.

Incoming calls will use the Find Me feature to ring Nomorobo, which then identifies calls from known robocallers and answers the call for you. Your home phone will ring once letting you know that Nomorobo has answered and stopped the call. All other calls will continue to ring to your home phone as normal.

  • Free - There is no charge to Optimum Voice customers
  • One time setup - Activate Nomorobo on your Optimum Voice phone service
  • Easy to control - Use the Optimum Voice portal to turn the service on or off at any time
  • 24/7 real time protection - Stops more than 900,000 known robocallers while allowing legitimate calls, such as school announcements or prescription reminders, to get through
