QoS with Office Communicator 2007 R2

I’ve recently been doing some testing with Quality of Service (QoS) at the workstation level to see if we can get improvements with audio / video quality with Office Communicator 2007 R2. After making the registry change (HKEY_LOCAL_MACHINE SoftwareMicrosoftRTCTransportQoSEnabled) and starting the QoS RSVP service I did some testing. The video and audio quality on peer to peer calls was severely degraded to the point where a conversation was not possible and the call would often disconnect after a few seconds.

In summary, don’t use Quality of Service (QoS) at the workstation level with OCS, stick to doing prioritization at the network level….
