The Effects of Caller ID Authentication on Answer Rates
Caller ID authentication, or verifying the accuracy of a phone call’s origin, is essential for businesses placing outbound calls to leads. Businesses prioritizing caller ID authentication can improve answer rates, increasing trust among call recipients who are less likely to answer calls from unknown or spam-flagged numbers.
Call Origination Process
Call origination refers to the party that initiates a phone call. This process works differently between landline telephones and VoIP calls. POTS and VoIP are two ways in which a call can originate.
POTS Call Origination
Plain Old Telephone Service (POTS) is the first step in initiating a phone call. This process is used for landlines, requiring the user to “seize” the line or circuit before the call can be established. The caller hears a dial tone when using a dial-up circuit and can then enter the phone number to place a call. POTS is being phased out as more modern and effective technology, such as VoIP, has emerged.
VoIP Call Origination
In contrast, VoIP call origination uses voice over Internet protocol, which originates on the Public Switched Telephone Network (PSTN) and is then delivered to a VoIP device or system. VoIP uses packet switching technology to originate calls, converting voice signals to digital data packets and transmitting them through an internet signal.
Caller ID Authentication Explained
The STIR/SHAKEN frameworks work to verify the authenticity of a call’s origination. This informs the network providers whether the call can be trusted, if they should be skeptical, or if they should block or flag the call for the consumer.
STIR, which stands for Secure Telephone Identity Revisited, refers to a set of technical standards that verify a caller’s authorization to use a specific phone number. Meanwhile, SHAKEN (Signature-based Handling of Asserted information using toKENs) provides a framework to build trust between callers and recipients.
Purpose of Caller ID Authentication
Caller ID authentication was developed to thwart call spoofing attempts made by scammers and robocallers. This process has made some impact. However, it comes with its drawbacks. The system has negatively affected some legitimate businesses.
Negative call labels can potentially damage your company’s reputation. Erroneous call labels can lead to frustration, reduced ROI, and degrade customer confidence in your brand. In turn, these can also cause negative side effects on your business, such as:
- Lower answer rates: Fewer answered calls due to negative call labels means missed opportunities for your business
- Calling agent burnout: Agents will become frustrated with lower answer rates and lose motivation and productivity
- Wasted time and resources: Consumers not answering their phones means your staff are wasting time and resources
- Reduced brand impression: Negative call labels can change the way customers view your brand (in a negative light)
- Eroded consumer confidence: Most customers assume flagged calls are scams, reducing their confidence in your business
Solutions to Maintaining an Accurate Caller ID
Erroneous call labels can negatively impact legitimate businesses, but there’s plenty you can do to take matters into your own hands. Some ways you can help your company maintain an accurate caller ID include:
Scan phone numbers regularly
It is vital to scan phone numbers regularly for flags that could hinder your business. Using a system such as Caller ID Reputation can help you save time and easily monitor potential negative call flags.
Engaging in ethical dialing habits and maintaining data hygiene
Ethical dialing habits involve compliance with call regulations and training agents to adhere to best calling practices. For example, agents should avoid calling numbers on the DNC registry and refrain from placing calls during specific hours of the day, such as late in the evening hours or early in the morning. Use updated phone lists for proper data hygiene and keep info up-to-date to avoid potential call flags.
Audit rich call data and maintain an A-attestation rating
Audting your Rich Call Data regularly ensures your caller ID remains accurate for consumers. In addition, maintaining an A-attestation rating in the context of the STIR/SHAKEN protocol can help build trust for your company, indicating the lowest possible level of risk.
