1. NTS: TURN TCP Connectivity
This tests if your device can connect to Twilio’s TURN server using TCP (Transmission Control Protocol).
Why it matters:
TURN servers help maintain video call quality in restricted networks. Passing ensures a higher chance of a stable connection.
2. NTS: TURN TLS Connectivity
This tests if your device can connect to Twilio’s TURN server using TLS (Transport Layer Security).
Why it matters:
TLS adds an extra layer of security to your connection. Passing means your connection is encrypted and secure.
3. Voice: Bandwidth
This determines how many simultaneous Twilio Voice calls your network can support.
Why it matters:
This ensures that your internet connection is fast enough to handle high-quality voice calls without interruptions.
4. Voice: Test Call using PCMU
This tests your ability to make a voice call using the PCMU codec
Why it matters:
A successful test means your voice calls will work with excellent sound quality.
5. Voice: Test Call using Opus
This tests your ability to make a voice call using the Opus codec (a more advanced audio compression format).
Why it matters:
Opus provides even better sound quality than PCMU, especially in variable network conditions.
6. Video: Insights Connectivity
This verifies if your browser can connect to Twilio’s Insights endpoint, which collects call statistics and quality information.
Why it matters:
This connection helps monitor and optimize your video call experience in real time.
7. Video: Signaling Connectivity
This tests your connection to Twilio’s signaling endpoint, which manages the setup and control of video sessions.
Why it matters:
Passing this test means you can successfully initiate and manage video calls.
8. Video: Test Group Room with TURN
(Do not be concerned if your computer fails this part of the test)
This tests your ability to connect to a group video room using a TURN relay server.
Why it matters:
TURN servers act as a backup when direct peer-to-peer connections are not possible. Failing may indicate network restrictions (firewalls) that could affect your video calls in group settings.
9. Video: Test Group Room without TURN
(Do not be concerned if your computer fails this part of the test)
This tests your ability to connect directly to a group video room without using a TURN relay server.
Why it matters:
Failing this test means your device couldn’t establish a direct connection, which may lead to issues in group video sessions.
