Hello all,

 

Poly VVX and Trio phone support differentiated services code point (DSCP)

 

DSCP allows specification of a datagrams desired priority and routing through low-delay, high-throughput, or highly-reliable networks.

 

VIa the Web Interface Settings > Network > QoS the Audio RTP, Video RTP or the Call Control can be set for the IP DSCP.

Configuration File via Provisioning Server:

 

<test 		qos.ip.callControl.dscp="24"
		qos.ip.rtp.dscp="46"
		qos.ip.rtp.video.dscp="34"/>

 

Troubleshooting:

 

Verify this using Wireshark with the following example filter:

 

(ip.dsfield.dscp == 24) || (ip.dsfield.dscp == 46) || (ip.dsfield.dscp == 34)

Skype for Business:

 

Quality of Service for Audio and Video Calls on VVX Phones


When the Quality of Service (QoS) setting is enabled on the Skype for Business server, VVX phones receive the Differentiated Services Code Point (DSCP) value from the server for Quality of Service (QoS) of audio calls placed or received from phones registered to the Skype for Business server.

 

Utilizing a Skype for Business server the value can be inbound provisioned via the Skype server. A partial backup looks like this:

 

	<CALL_SERVER
		...
		lync.qos.dscpVoice="46"
...	/>


The Skype for Business server does not provide in-band provisioning for DSCP for QoS of video calls for outbound video streams.

 

When video is enabled on VVX 501, VVX 601 or Trio phones, provision the phones to receive DSCP for QoS of audio calls using the above parameter qos.ip.rtp.dscp and for video calls using qos.ip.rtp.video.dscp.
