Identifying the Symptom: Call Dropped Unexpectedly

One common issue developers encounter is calls dropping unexpectedly during a session. This symptom is characterized by an abrupt disconnection of an ongoing call without any user intervention or error message.

Exploring the Issue: Network Instability or Session Timeout

The primary causes of unexpected call drops are often linked to network instability or session timeout settings. Network instability can lead to packet loss, affecting call quality and causing disconnections. Similarly, session timeouts can terminate calls if the session duration exceeds the configured limit.

Network Instability

Network instability can occur due to poor internet connectivity, high latency, or packet loss. These factors disrupt the continuous flow of data packets necessary for maintaining a stable call connection.

Session Timeout

Session timeouts are predefined limits set to terminate calls after a certain duration. If not configured correctly, they can lead to premature call termination.

Steps to Fix the Issue

Ensuring Stable Network Conditions

• Check your internet connection for stability and speed. Use tools like Speedtest to verify your network performance.
• Minimize network congestion by reducing the number of devices connected to the network during calls.
• Consider using a wired connection instead of Wi-Fi to reduce latency and packet loss.

Adjusting Session Timeout Settings

• Review your application's session timeout settings. Ensure they are configured to accommodate the expected duration of calls.
• Refer to the Telnyx API documentation for guidance on adjusting session timeout parameters.
• Test the changes in a controlled environment to ensure they resolve the issue without introducing new problems.

Conclusion

By addressing network instability and configuring session timeouts appropriately, you can significantly reduce the occurrence of unexpected call drops. Regular monitoring and testing will help maintain optimal performance and user satisfaction.
