What troubleshooting steps can be taken for audio issues in 3CX?

Audio issues in a 3CX system can stem from a variety of causes including network configuration, firewall settings, and the individual configurations of endpoint devices. The complexity of audio problems often necessitates a systematic approach to troubleshooting, which is why checking network settings, firewall rules, and endpoint configurations is a critical step.

When audio issues arise, it is essential to verify that the network is properly configured to allow VoIP traffic. This includes confirming the Quality of Service (QoS) settings, which prioritize voice data over other types of traffic, as well as ensuring that any necessary ports are open in the firewall to avoid blocked communication.

Endpoint configurations also play a vital role. Each device (phones, softphones, etc.) needs to be correctly set up, ensuring they are registered with the 3CX system and that their settings match what is necessary for optimal operation. Addressing these configurations can often directly resolve audio issues.

While other options may seem like potential solutions, they do not address the root causes as effectively. Restarting the 3CX server may temporarily resolve issues, but it does not tackle underlying configuration or network problems. Performing a factory reset on endpoint devices could erase valuable settings and create more complications during reconfiguration. Finally, contacting the internet service
