At Spearline we are proud to have developed a unique approach to number testing developed over the last eight years. Our tests have developed in response to our customers’ needs and we believe that they provide the best insight available into the audio quality experienced by the end user. This in turn reveals the quality of the networks, pathways and carriers. So what exactly do we do and how does it help?


Unlike other testing tools we analyse audio quality right across the whole network from point of origin to termination. We test numbers terminating over different carriers in multiple locations. Each number has years of testing data behind it allowing us to accurately compare your company’s performance against what we would expect.

We have carried out millions of customer tests using multiple carriers worldwide. Our dataset for benchmarking performance is unrivalled and using an international standard PESQ (Perceptual Evaluation of Speech Quality) test we can make a compelling case to the carrier when it comes to troubleshooting issues.

Too often tests are based on network analysis and make assumptions that if there is no packet loss, low latency and jitter, then the audio that traverses that network will be of high quality. Often this is not the case and our audio tests can help identify other issues such as transcoding.

We therefore not only help identify the issues for you, we advise you on the standard of audio quality you can expect to reach and we help you to achieve it. We tailor our solutions to meet your specific needs and we can customise reports, web interfaces and integrate with your NOC if needed.

We provide a no obligation free trial period including support for our testing products to see which one suits your needs best. Contact us today and get testing.
