Nomorobo is a great service, however keep in mind that it uses a technology that relies on the ability to detect dialers making high volume of calls within a short period of time.  


HQTelecom’s Anti-Scam filters complement Nomorobo’s filters by focusing on targeting scam artists doing low volume of calls.  Below is a comparison table outlining some of the key similarities and differences among these services:
