This article explains what these emails mean, the key metrics they include (like jitter, packet loss, and round-trip time), and simple troubleshooting steps such as restarting the internet or router to fix connectivity problems. If needed, organizations can also request to disable these emails for all users via support. Clientside Error Emails are automated notifications sent when FreJun detects internet issues on the user’s side during a call session—most commonly due to **internet connectivity problems**. These emails help users understand why a call may have been disrupted or failed, and typically include diagnostic metrics such as: - **Jitter**: Variability in packet delivery time - **Packet Loss**: Percentage of data packets that didn’t reach their destination - **Round Trip Time (RTT)**: Time taken for data to travel from the user’s device to the server and back #### Troubleshooting Tips When a user receives a clientside error email, it means the issue is likely with their internet connection. To resolve it, we recommend: - Restarting the internet connection - Rebooting the Wi-Fi router - Ensuring a stable network These steps often resolve temporary connectivity issues and improve call quality.   **If your organization prefers not to receive these emails, you can submit a request to support@frejun.com to have them disabled across the entire organization.** **[Sign Up Now](https://product.frejun.com/signup)** -
