Unravelling the Anatomy of Spam Calls: How Do They Work and Why They Persist


The digital age has brought us numerous conveniences beyond measure. While the internet has always been divided on several issues, there's one thing we can all agree on phishing and spam calls are a real nuisance and potentially dangerous.

In this blog, we will walk you through the anatomy of this plague to help you be better prepared to avoid falling prey to them. And will also give you a potential solution that stops unwanted calls once and for all.

Spam Call: What are they, and How do they work?

Spam calls are any unsolicited communications, whether for legitimate or unlawful purposes. These spam callsare increasing in number as the spammers are getting tech-savvy by the minute.

Today, scammers use a myriad of tech to try and con people. The following are the most common types of spamcalls:

Automated Calling Software:

Automated Calling Software allows these scammers to make thousands of calls a day. They are usually pre-recorded automated calls (hence the name robocalls) designed to mimic a legitimate entity.


The more observant among us can tell when an incoming call's number does seem odd. Spammers know this,too, and hence they try to manipulate caller ID to make the call appear legitimate. This technique is called Spoofing.

VoIP Calls:

VoIP technology allows scammers to hide their real identity and location, and since these calls are made via theinternet, they are cheap and easy, too. Combine this with Spoofing, and it's hard to tell if a call is a Spam Call or not.

What's the Reason Behind Spam Calls?

Well, while there are different types of spam callers, they all have one thing in common: they want to make money from you. Some of them are scammers who try to deceive you into giving them your personal or financial information. Others are telemarketers who try to sell you products or services that you do not need or want.

Why are Spam Calls Hard to Mitigate?

These spam calls cross state, national, and international borders. Technology has made it easier for malicious communications to cross borders, making enforcing laws against them difficult.

Add to the fact that each country may have different definitions, rules, laws, and systems for dealing with spamcalls, and you see the challenge.

So What's the Solution?

The current state of things makes it impossible to eradicate the menace of spam calls as a whole. That said,mobile carriers are banking on Artificial Intelligence and Machine Learning Algorithms to predict patterns and warn users of potential spam calls.

However, this approach is still being developed, and it will take time to address this menace on its own accord.One possible solution to tackle spam calls immediately is to take matters into our own hands. Using a virtual number provider like Doosra can effectively tackle the issue of spam calls.
