Computer cpu load increased with ip phones

[Mr_41Magnum]

Hi,

our computers with ip phones (8028 and 38) have an increased cpu load when the phones are in between. This result is reproducable, and when I bypass the phone, the cpu load goes reliably down.
Do the phones start any process on a computer while connected? I don't see anything suspicious in the task manager

did you check the process of your pc? as far as i know the ip phones may effects only on your network interface

Which process? There ist no new one. I only see the green cpu bar that has 1-5% idle load, and when I connect the phone, the cpu load raises to 30% and holds that level, and no new processes or any existing processes can be held responsible
