Case Study: Verbling gains call quality insights with Callstats.io

Verbling gains insights into every call using callstats

Verbling, a San Francisco-based online language education marketplace, relies on WebRTC to connect tens of thousands of students with teachers each month. As a small team, Verbling faced recurring issues with firewalls, connection quality, ISPs, and limited visibility into call problems, making it difficult to diagnose audio and video issues effectively.

To address this, Verbling implemented callstats.io’s callstats for call analytics and performance monitoring. The integration was seamless with their SDK, and the team received initial data within a day of deployment. With callstats.io, Verbling gained clear insight into call setup delays and connection disruptions, improved support and diagnosis, and could focus on its core business of connecting teachers and students.
