I have a recent problem that i dont really understand what caused it. We have had a cisco UC520 phone system for almost 1 1/2 years now and everything is fine. All of the sudden when a user has a large file to download for a sustained amount of time the IP input process goes extremely high on the cisco box and doesnt allow the phone system to make calls or receive. Is their anyway of limiting this process? The phone should be the highest priority for us. I read an artivel on ciscos website http://www.cisco.com/en/US/products/hw/routers/ps359/products_tech_note09186a00801c2af3.shtml
but havent been able to figure it out.
