Understanding the Issue
VoIP calls can be a real nuisance, and it's essential to understand the issue to effectively block them. VoIP spoofing is a trick used by scammers and telemarketers to hide their true identity by changing the caller ID information.
Telemarketers and scammers often use VoIP technology to make calls because it's low-cost and easy to do over the Internet. This makes it difficult for recipients to identify and block these unwanted calls. VoIP calls often come from automated systems, which can be particularly annoying.
What is Spoofing?
Spoofing is a trick used by scammers and telemarketers to hide their true identity by changing the caller ID information shown on the recipient's phone. They do this by using VoIP technology, which lets them adjust the data packets that carry caller ID details.
VoIP spoofing makes it look like the call is coming from a known or trusted number, increasing the chance that the recipient will answer the call. This can be a local area code, a reputable business, or even a government agency.
Neighbor spoofing is another trick used by bad callers, where they fake their caller ID to look like they are calling from a local number, often with the same area code and prefix as the person receiving the call. This makes the call look like it's from a familiar or local number.
VoIP calls often come from telemarketers, scammers, and automated systems due to the low cost and ease of making these calls over the Internet.

Telemarketing Abuses
Telemarketing Abuses are a real nuisance, and they often involve unwanted calls from marketers trying to sell products or services. These calls can interrupt your daily activities and ignore your privacy preferences.

27 million Americans have fallen victim to identity fraud scams, which often involve clever scams where the caller acts like they are from a real organization, like a bank or government agency. These scammers aim to trick you into giving personal information or making unauthorized transfers.
To protect yourself, use your VoIP service provider's security features, like fraud detection systems that can identify and block suspicious activities.
