Diagnosing connection issues with vMix Call

vMix Call utilises the WebRTC capability on web browsers to enable video calls over the internet.
As WebRTC needs to establish a direct network connection between the caller and vMix, there are a few things that may block this
from taking place that we have noted below:

1. 3rd Party Antivirus / Security software installed on the caller and/or vMix PC.

This includes antivirus/security software from Norton, Symantec, Mcafee and others.
We strongly recommend uninstalling these where possible. The free Windows Defender anti-virus in Windows 10 does not interfere
with vMix Call and provides strong protection against viruses without the need for 3rd party software.

2. Restrictive corporate network firewall policies.

Some networks are heavily locked down and only allow basic web traffic through. This will prevent vMix Call from establishing a connection.
The document below can be forwarded to your network administrator to ensure special access is given for vMix:

3. Slow internet speeds

When establishing a call, vMix will start sending return audio and video to the caller based on the Video Bandwidth setting when setting up the input in vMix.
It is recommended to set this to the lowest possible setting (Mobile 300Kbps) when experiencing bad video quality or audio from the caller, as setting this too high
may overwhelm the internet on the caller's end and prevent video coming back as a result.
