I'm sorry to hear that you're experiencing issues with the voice call feature in Session. While I don't have access to specific information about the app's infrastructure, I can provide some general insights that might help you understand the possible reasons behind the problem and suggest some potential solutions.
1. Network Connectivity: The success rate of voice calls can be affected by the quality and stability of your internet connection. If you have a weak or unstable network connection, it can lead to dropped calls or poor call quality. Try switching to a different Wi-Fi network or using a cellular data connection to see if that improves the situation.
2. Firewall or Network Restrictions: Some networks or firewalls may block or restrict certain types of internet traffic, including voice calls. This can prevent Session from establishing a connection for the call. If you're using Session on a restricted network, such as a corporate or public Wi-Fi, try using a different network or contact the network administrator to see if they can whitelist Session's traffic.
3. Device Compatibility: The voice call feature in Session may have specific requirements in terms of device compatibility. Make sure you're using a supported device with the latest version of the app installed. Outdated software or incompatible devices can cause issues with the voice call functionality.
4. Server Load: If the Session servers are experiencing high traffic or load, it can affect the performance of the voice call feature. This could result in dropped calls or difficulty in establishing connections. Unfortunately, this is something that is beyond the control of individual users. In such cases, it's best to be patient and try again later.
5. Feedback and Support: If you've tried the above suggestions and are still experiencing issues, it's recommended to provide feedback to the Session developers. They may be able to provide more specific assistance or investigate the problem further. You can reach out to them through the app's support channels or check their website for any known issues or troubleshooting guides.
Remember that troubleshooting technical issues can be complex, and the above suggestions are general in nature. It's always best to consult the official support channels or documentation provided by the app developers for more accurate and up-to-date information.
