I have a VOIP wired connected to my C6900; the company said I need to set it to 1st priority in the modem-router. I can't find how to do it. Please help.
I don't believe the C6900 has qos or device prioritization. I don't have one so I can't say 100% but the manual doesn't show anything for those services.
What issue are you having that you think it needs this?
