Lync Phone Edition QoS

The final client type that can use QoS settings is the Lync Phone Edition client, which can run on third-party partner hardware. Lync Phone Edition settings are determined through in-band signaling to the devices. In addition to a DSCP value for audio traffic, the Lync Phone Edition clients also support 802.1p.

To set the Lync Phone Edition QoS settings, use the following command on a Lync server:

Set-CsUcPhoneConfiguration -VoiceDiffServTag 46

Set-CsUcPhoneConfiguration still includes the Voice8021p parameter used to define a 802.1p class, but it has no effect on devices in Lync Server 2013. Instead, use DSCP values for providing QoS markings.
