The video/audio is not choppy, just poor quality video resolution. What should we be looking at to troubleshoot? Thanks,

Most providers offer good downstream but bad upstream. Check the performance of your firewall/router. Try to disable realtime virus scanning. Check system I/O to disk.

At our studio we are using a Cisco asr1001X router with tons of pipe on a fiber circuit. We can see the UDP stream coming in at about 1.4Mbps for each caller.

But it is still WebRTC traffic. I prefer MS Teams with NDI. I had a beter quality experience with that, than vmix call. I use vmixcall as backup. Is evrything wired? Or a part wireless? Is QOS enabled?

For vmix call the cpu performance is important. Olf i7 (5 years) runs better with vmixcall on a brand new i5. I run my vmix host system on an i9 9th gen with 2 ssd in a raid 0 setup. I still prefer teams

How did you solve the audio being brought on all channels. Do you have someone mute on the Teams side? Did you find a way to talk back without going to active speakers?

Per Martin's suggestion, I've been forcing the guest's bandwidth and it has cleared up the signals in most cases. I find 2000 Kbps to be an adequate bitrate for a 720p webcam.
