Whey you make or receive a phone call using the Lead Hero VoiP calling system, the technology making it work behind the scenes is Twilio.
If Twilio's voice calling quality is not sounding very good, this might be affected due to various reasons. Some of these might be:
-
Network Issues: Problems with your network can significantly affect call quality. This includes poor Wi-Fi signal, slow internet speed, latency, or packet loss. You should check the network condition at both ends of the call (your end and the receiving end).
-
Device Issues: Sometimes, the issue might be with the device being used for calling. An outdated or faulty device, or a device with poor microphone or speaker quality, can contribute to poor call quality.
-
Twilio Server Issues: Occasionally, the issue might originate from Twilio's side, such as server outages or technical issues with the VoIP service. Although this is less common, it's worth checking Twilio's system status page.
-
Bandwidth Limitations: If there's not enough bandwidth available, the quality of VoIP calls can degrade. This might be because too many people are using the same network, or because other high-bandwidth activities (like streaming video) are occurring at the same time.
-
Configuration Issues: It might be that there are some incorrect settings within your Twilio configuration that are causing problems with call quality. This could include issues like incorrect codec settings or routing problems.
-
Firewall Issues: Sometimes, firewall settings can interfere with VoIP traffic, which can result in poor call quality. Make sure your firewall settings are correctly configured to allow VoIP traffic.
To address these issues, you could try the following:
- Test your network connection and ensure you have a reliable, high-speed internet connection.
- Use the latest and high-quality devices for calling.
- Monitor Twilio's system status page for any ongoing issues.
- Limit other high-bandwidth activities during calls, or upgrade your internet plan to provide more bandwidth.
- Review your Twilio settings and ensure everything is correctly configured.
- Check your firewall settings and adjust them if necessary to allow VoIP traffic.
Remember to troubleshoot the issue step by step, so that you can pinpoint the exact cause and rectify it accordingly.
