I am unable to hear anyone or use my microphone in Rainbow 6 Siege. My ISP is Stormfiber and I have static IP and so all ports are open but the voice chat still doesn't work. I contacted Stormfiber and they told me that PTA's WMS (Web Monitoring System) is causing this issue as VOIP traffic comes under grey traffic and so is strictly monitored. Is anyone else having this issue on other ISPs?
