How Analytics Engines & Audio Fingerprinting Mark Sales Calls as Spam

In the modern, fast-paced world of sales, businesses continually strive to connect with potential customers and grow their brands. However, an emerging issue that many sales-focused organizations face is the mislabeling of their outbound sales calls as spam. This mislabeling can stem from using analytics engines and audio fingerprinting technologies to identify and block scam calls. But how does this happen? And what can your business do to prevent it? That's what we'll explore in this blog post.

The Rise of Scam Calls and the Response of Technology

The Federal Trade Commission received more than 230,000 reports about phone call fraud in 2022. This trend has led to increased technology to combat these scam calls, including analytics engines and audio fingerprinting.

Carrier Analytics Engines

Analytics engines collect data about calls made on a network, allowing them to identify patterns common among scam calls. For instance, they might discover that scam calls frequently originate from numbers that place an unusually high number of outbound calls per hour. These engines then label these numbers as "spam likely" or similar, helping to protect consumers from potential scams.

Carrier Audio Fingerprinting

On the other hand, audio fingerprinting uses algorithms to analyze sound files and create digital summaries of their content. This technology effectively identifies scam calls that use the same recorded scripts to reach as many consumers as possible. When it detects the same content from different numbers, it infers that those numbers are likely making scam calls and labels them accordingly.

The Unintended Consequences for Legitimate Sales Calls

While these technologies are impressive and effective at reducing scam calls, they aren't perfect. Legitimate businesses making outbound sales calls can sometimes fall foul of these systems.

A business making a high volume of outbound calls or using similar scripts for efficiency can inadvertently trigger these systems. Suddenly, potential customers might not answer your calls because their caller ID screens display warning messages. This mislabeling can severely damage your call answer rates, the effectiveness of your sales efforts, and, ultimately, your business reputation.
