Cyara helps businesses connect with customers using automated, proactive global number testing.
AI validation in number testing uses machine learning and automated verification to analyze phone call results, distinguish genuine failures from false alerts, and provide accurate insights into call quality issues, confirming businesses only receive alerts when real problems occur.

The importance of number testing
For global organizations, testing and monitoring inbound and outbound phone lines to confirm they are answering customers’ calls is critical. It’s also crucial to verify these lines provide the highest possible audio quality to customers. They should function flawlessly, free from issues such as jitter (variation in packet arrival times causing choppy audio), latency (delay between speaking and hearing), or packet loss (missing data packets that degrade call quality).
Monitoring a global network of numbers requires constant vigilance. Most solution providers only monitor number performance within your internal network. However, Cyara Voice Assure adopts a comprehensive approach, testing ‘outside-in’ and replicating the experiences of your customers globally. This means that we thoroughly test not only your internal network, but also the external network. The stability and reliability of your external carrier’s networks is an example of this.
It’s also important to note that local contact numbers can only be dialed from their respective countries. Previously, organizations often depended on family and friends abroad, or even freelancers to validate the efficient operation of their numbers. While this gave a subjective performance indicator, the results were typically inconsistent and often unreliable.
Without continuous monitoring, organizations generally only discover issues after an influx of complaints from callers. What makes this more concerning is that research shows only a small percentage of customers will complain if they experience an issue. This suggests that any problem will likely impact many customers before the organization becomes aware of it.

These alerts include full call detail records (CDRs), enabling your team to precisely understand when and where the issue is occurring. Thus, drastically reducing troubleshooting time and resource requirements. The Voice Assure solution empowers you to proactively, and accurately stay ahead of any issues before they can negatively impact your customers.
Our Intelligent Alerting system
At Cyara, we understand the importance of confirming your team only receives alerts during real issues. This also prevents the often time-consuming and laborious nature of false alerts. To achieve this, we leverage AI validation and human verification to automatically validate all test results. This validates alerts are issued only when a true problem occurs and your pre-specified thresholds are not met.
Our Intelligent Alerting system will conduct a series of automated tests as soon as it detects a problem. It enhances the understanding of the specific number’s behavior, ensuring alerts are triggered only when necessary. This allows your IT and network operations teams to better focus on addressing other issues or potential improvements.
What is Project Gamma?
Project Gamma is Cyara’s proprietary AI validation system that combines deep learning, automatic speech recognition, and business logic to deliver highly accurate phone number testing results.
Core components:

- Business logic rules for contextual result validation
At Cyara, we are dedicated to delivering the highest quality results to all our customers. As part of this commitment, we continuously seek ways to optimize processes and enhance efficiencies for our customers and team. That’s why we developed Project Gamma. Leveraging Gamma allows us to provide accurate results to our customers more quickly while maintaining the highest quality standards.
Project Gamma is a powerful tool that brings an unprecedented level of accuracy to results, with a particular emphasis on failed tests.
Our sophisticated AI is capable of automating numerous tasks such as:
- Reduces false alerts by verifying audio quality: Gamma checks whether failures relate to audio quality issues, out-of-office messages, or other announcement messages, directing your team straight to the source of the issue.
- Validates backend responses before marking failures: Where a fail occurs, Gamma checks the backend responses from your numbers and providers before marking any call as unsuccessful.
- Verifies quality scores meet thresholds before alerting: Gamma verifies that your audio quality scores are below our benchmarks or your pre-specified threshold before issuing your team with an alert.
- Confirms issues through automated re-runs: Gamma automatically re-runs tests multiple times before marking them as failed, ensuring that the issue is not a one-time event and is replicated in subsequent runs.
Continually Improving and Evolving
Project Gamma provides numerous advantages, especially in terms of efficiency and improving handling times. It also improves the accuracy of test results and minimizes false alerts.
With millions of calls flowing through our infrastructure every month, Project Gamma has extensive training in a comprehensive range of test data and insights.
