Do you want more of your customers to pick up your phone calls? Use trusted calling solutions to avoid getting marked as spam by carriers and users.

How many times has it happened that you called a customer for feedback, and they did not pick it up because they thought it to be spam?

Ask your tele-calling team, and you will know that there have been numerous incidents like this. So, what could be the solution? Using trusted calling.

What Is Trusted Calling?

Trusted calling is the technique to show the recipient that the call is coming from a reliable source, preferably a business company. It also tells them that a phone call is not spam. When companies opt for trusted call solutions, they can get their phone numbers registered and verified.

Also, it protects their numbers from getting mislabelled as spam likely. It has an overall positive impact on your business by increasing the rate of answered calls.

Importance of Verified Phone Numbers

Using verified phone numbers for business calling is highly significant. As you need those numbers to share business updates, promotional vouchers, and lucrative offers, it is best to avoid using any random numbers and go for the verified ones only.

Phone verification is necessary to protect your business reputation from fraudulent activities. Fraudsters often hide their own number and use others’ phone numbers for illegal activities. As a result, those numbers get marked as spam by the users. Verified phone numbers can protect you in such scenarios.

What Is SHAKEN/STIR Protocol and Why Is It Crucial

SHAKEN stands for Signature-based Handling of Asserted information using toKENs, while the full form of STIR is Secure Telephony Identity Revisited. Together, SHAKEN/STIR is a combination of protocols for fighting caller ID spoofing, 

These protocols work together to ensure the authenticity of a call and confirm that the caller ID info matches the actual caller. According to FCC (Federal Communications Commission,) all telephone service providers need to use this service. This protocol is vital due to the following reasons:

  • It helps to build trust with customers and increases the phone answering rate to a great extent.
  • The STIR/SHAKEN protocol protects the reputation of legitimate businesses. It assigns them a high score to ensure that these calls are not mislabeled as spam. 
  • It authenticates incoming calls to a user’s number and blocks unwanted spam calls even before reaching the recipient’s telephone. 
  • This protocol also detects robocalls containing pre-recorded messages and marks them as potentially fraudulent calls. It assigns them a low score to prevent them from reaching users’ phones.

Now, we explore some top trusted calling solutions to choose for your business.
