I need help with this. I changed ISP recently and the phone is by VOip. Now, the problem is that my internet speed is supposed to be 30MBPS, but with the cable modem connected to the VOip router, my speed drops to 18MBPS even if the phone is not in use.
Does anyone know how to get my speed back to 30MBPS when the phone is not in use ?

I know the speed is actually supposed to drop when the phone is being used, but not when it isn't...
