I now see objective voice quality PESQ scores on every number we test - visibility I didn't have before we started Spearline.

Arnie Chencinski, Senior Voice Network Engineer

Spearline gave us better visibility on the quality of our service, and allowed us to detect and solve issues much faster. It contributed to improving call quality and customer satisfaction.

Pierre-Baptiste Béchu, Tech Co-Founder

Spearline offers a quicker detection of issues and faster turnaround times that require less human resources.

The platform has been exceptional in our ability to drive carrier improvements, customer fault investigations and alerting of any country issues.
