BrightTALK always encourages testing for the best call experience possible. For further testing, we encourage those who use BrightTALK to test through the Twilio network testing tool found here.
Once one clicks on the test link, the test will run in a new browser window, displaying the diagnostics. For a seamless Webinar experience, please make sure you clear all the tests. Below we outline the meaning of each phase, error, what one can do to fix them.
The following table gives details on the most critical tests:
|
Network Parameter |
Description |
Possible Solution |
|
TURN UDP Connectivity |
This establishes UDP connectivity from your Chrome browser to the TURN servers. |
If the UDP connection phase fails, it indicates that your WebRTC session did not establish a connection over UDP. Port 3478 & 443 are required for TURN and STUN WebRTC Protocols. |
|
TURN TCP Connectivity
|
This establishes TCP connectivity from your Chrome browser to the TURN servers. |
If the UDP connection phase fails, it indicates that your WebRTC session did not establish a connection over UDP. Port 3478 & 443 are required for TURN and STUN WebRTC Protocols. |
|
Bandwidth |
This phase test will check the number of simultaneous clients your network can support. |
Make sure to check the output log for the highest, lowest, and average bandwidth. This is important as this will give one the number of simultaneous connections that Twilio can support within your network.

Test Talk using PCMU & Opus
|
This phase of the test will check the browser's ability to make calls with the Client. Please make sure your microphone is not blocked and, is enabled. This test requires access to your microphone.
|
This test could fail if your browser or Operating System is out-of-date. Please make sure to use an updated Operating System version and the latest version of Chrome. |
After performing the test above, for best connectivity:
- Make sure to run the network test each time. Make sure to run the test on the local machine that will be used for the Talks.
- Please note that Talks is only optimized for a Desktop or laptops.
- Please note Talks is not optimized for Mobile phones or Tablets.
- Please make sure that you clear the major network tests specified above and apply the solutions listed.
- If any of the tests fail, this could be a broad indication of firewall restrictions. Here, TCP, UDP, or both could have failed. Ensure that you whitelist the BrightTALK domain and ports mentioned.
- If possible, increase the bandwidth by connecting an ethernet cable to your laptop or disconnecting bandwidth-heavy applications in your household or workplace. This will resolve many Talks issues with regards to calling latency and, quality.
- Check if other applications are consuming total available bandwidth. If yes, please ask your IT administrators to allocate most of your capacity to priority applications such as Chrome. This will allow a smoother Talks experience.
- Please make sure to check for possible Packet loss issues. There should be no packet losses.
- To use Talks, we recommend a minimum of 6Mbps download speed and 2Mbps upload speed.
Best Practices and Recommendations:
- Channel Preference
- Try and use a LAN connection instead of wireless. Generally, the wireless capacity can add to further packet loss and, exacerbate call quality issues.
- If you do or are using Wifi, reduce conflict by the number of devices on the same network.
- Latency can be reduced by reducing the amount of data being transferred during a Talks session. Make sure to dedicate total bandwidth to the Talks session.
- Best Network Usage
- In a Talks session, please make sure to use higher bandwidth connections. Through evidence, we have noticed lower bandwidth adds to latency issues. Issues involve processing and network transfers.
- Browser Preference and Settings
- Please make sure your browser is Google Chrome. Talks will work best with this browser—upgrade the browser to the latest version and, use the latest version of Chrome at all times.
- Every Talks session one has, please make sure to clear your cookies and cache before starting.
- Make sure to log out of other applications before starting the Talks.
- Ensure that all permissions are allowed. For example, edit your browser's site settings and allow the BrightTALK website components. Make sure all dependencies such as the microphone, camera and sound are enabled.
- RAM space can be heavily used whilst having many tabs open. Make sure only to use a few tabs whilst preparing and using Talks. Having too many tabs open can take up RAM space which is vital for applications such as Chrome to run efficiently.
- Please make sure to disable Google Extensions, if necessary. Sometimes, Google Extensions can interfere with the Talks experience.
- Headset Preference (If used and necessary)
- Always use a high-quality wired headset. We recommend you to use a USB for the transfer of audio quality.
- PC settings
- Try to limit intensive applications when running a Talks session.
- For a Talks session, try disabling Anti-Virus software.
