In an age where communication is critical for both personal and business interactions, understanding how phone calls are routed is essential. The attached graphic illustrates a simplified call flow, emphasizing the importance of STIR/SHAKEN passports and the least cost routing (LCR) model. These concepts play a crucial role in ensuring that calls are delivered securely and efficiently, impacting the quality of communications and customer trust.
At the center of the call flow is the STIR/SHAKEN Passport. This passport contains vital identifying information that confirms the authenticity of the call's origin. When a call originates, the STIR/SHAKEN system generates a token that acts as a digital signature, verifying the calling party’s identity. This is particularly important in today’s telecommunications environment, where spam and fraudulent calls are rampant.
When a call is initiated, it goes through a process that involves generating the STIR/SHAKEN passport. This passport ensures that the call is legitimate and helps prevent caller ID spoofing, a common tactic used by scammers to mislead recipients about the identity of the caller.
The graphic illustrates that once the call is authenticated, it is routed through various carriers labeled A, B, C, and D. 100% of the industry operates on the LCR mode, which means that calls are routed through the carrier that offers the lowest cost for the call path. While this approach can save money, it also poses risks.
A critical aspect to consider is that 60% of the time, the identifying data is changed between the origin and delivery of the call. This means that as the call traverses through different carriers, the original identifying information can be altered or stripped away. Such manipulation can undermine the trustworthiness of the call, leading recipients to question the legitimacy of incoming calls.
The STIR/SHAKEN framework is a crucial component of ensuring call integrity. It not only authenticates the identity of the caller but also works to maintain the integrity of the call as it passes through various networks. This system provides a safeguard against fraudulent activities and enhances the overall security of phone communications.
For businesses, the implications of this call flow are significant. Companies rely on phone communications for vital operations, and any disruption or lack of trust can lead to lost opportunities. If consumers cannot trust that the call they are receiving is legitimate, they are likely to avoid answering calls from unknown numbers.
While LCR can be an effective way to manage telecommunications costs, it also presents challenges. As calls are routed through the most cost-effective carriers, the potential for data manipulation increases. This reality necessitates the need for businesses to implement robust monitoring and verification systems.
To navigate the complexities of call flow and ensure reliable communications, businesses should consider the following best practices:
Adopt Branded Caller ID (BCID): By using BCID, businesses can present their brand name and logo during outbound calls. This visibility helps recipients recognize legitimate calls and increases the chances of engagement.
Implement Monitoring Solutions: Investing in monitoring tools that track the performance and integrity of call paths can help identify issues related to data manipulation early on.
Engage with Trusted Providers: Collaborating with telecom providers that prioritize security and compliance can enhance overall communication reliability.
