poor inbound auido quality T5XW
We have a bunch of T54W and T57W phones with the PC connected to the PC port on VLAN 1 and the Audio is on VLAN 50 all auto provisioned using the 3cx out of the box templates. Pretty regularly when on a call, the inbound audio will start to garble. The outbound audio is not impacted. We can reproduce this problem if we do a speed test on the PC while on a call indicating (to me anyway) that QoS isn't working correctly. If I insert a managed switch on the same LAN jack to separate the PC from the phone, the problem goes away. But, I obviously don't want to purchase POE switches for the whole company. Oddly enough, we don't seem to be able to reproduce the problem on a T46S.

Any ideas?
