Won't help. I've had multiple callers encounter trouble with what I guess WebRTC traffic due to browser extensions, "anti" virus software, VPN policies etc. Zoom etc. works fine. They usually fixed it by switching to a personal phone instead of a work laptop but in general, the situation is not tenable.

Not sure there would be a decent enough return on investment, especially if the other tools they regularly use provide more reliable service at no additional cost.
