An Internet Landline and VoIP Call Blocker
VoIP, also known as Voice over Internet Protocol, communication channels allow people to use an internet connection to make calls instead of traditional networks. This gives individuals the flexibility to speak with audiences using any internet-connected device — like laptops, smartphones, and tablets.
Nomorobo is compatible with internet landlines and VoIP technologies. Your days of dealing with scam messages, spam calls, and malicious individuals trying to steal confidential information are over. Take a safer approach to communication with software that safeguards your line from unnecessary risk.
Spam Call Blocker for Landlines to Protect From Fraud
Nomorobo uses the most advanced spam call-blocking technology to help you filter calls based on what you want to receive. Only when a legitimate call is detected will Nomorobo refer the call to you. Our software scans for robocalls and hangs up the landline when these unwanted calls come your way, saving you time.
Nomorobo enables you to use your landline connections as you normally would. A single ring that stops indicates a robocall was detected and ended for you. Any time you hear a call ring more than once, you should answer it.
