Calling is dependent on various hardware parameters and the browser options of your system where you are calling :
- It could occur that you may not be able to hear what the caller is speaking.
- It could occur that you do not hear anything.
- It could occur that you just hear a beeping sound.
Follow the below options to troubleshoot your system:
Remove and re-attach your audio device (headset/headphone, mic, etc) again to the system.
Open the following link in your Chrome browser and check if you have allowed access to your Microphone, Sound, USB device, MIDI device (Whichever is applicable. Sound and Microphone are a must)
Here, my Salesmate link is demo.salesmate.io
If allowed, refresh/reload (Ctrl/Command+Shift+R) the page and make a call.
It should work 😃
If it still does not work,
Open the following link: https://networktest.twilio.com/.
This will check your call settings, allow access to Microphone when prompted for.
If it is a PASS, refresh/reload (Ctrl/Command+Shift+R) the page and make a call.
It should work 😃

- Use ethernet and not WiFi. The wireless medium adds to the packet loss and can cause issues with call quality and hence must be avoided.
- If you are using WiFi, reduce packet conflicts by reducing the number of devices operating on same channel.
- Avoid transferring huge amounts of data in the same WiFi network as the voice because this can add to the latency.
- Use high bandwidth internet connection as a lower bandwidth adds to the inherent latency involved in algorithmic processing, network traversal etc.
- Local network conditions have the highest impact on voice quality. Make sure you have sufficient bandwidth and try using ethernet for voice data.
- If you have addressed the above issues and continue to have jitter related impact on your voice quality, you may consider configuring your router with QoS rules to prioritize traffic on the UDP ports ranging from 10000-20000. (You can read this great article on setting up QoS for VoIP in your network.)
- We recommend you use USB / 3.5mm headsets over bluetooth ones. Even while using bluetooth ones, it is better to connect to the USB dongle that comes with the headsets rather than rely on native bluetooth capabilities. This is because each browser behaves differently with different hardware vendors and it becomes impossibly difficult to troubleshoot such issues.
Steps to troubleshoot when you encounter problems with the phone channel
- Upgrade Browser and Flash to latest version.
- Ensure your network ports aren’t being blocked by Firewall / router / antivirus software. Check out the section “Firewall” under “Minimum Requirements” in this document for the ports to be opened.
- If your router supports QoS, prioritize UDP ports in the range 10000-20000, and the IP address of the sales reps making/receiving the calls. Tips on setting up QoS for VoIP in your network can be found here.
- Check your network latency with the Ping test site. If the grade is less than A, call quality might be degraded.
