Sending RTCP XR in SIP PUBLISH Messages

If you've enabled RTCP XR reporting where RTCP XR is sent in the RTP media stream (see Enabling and Configuring RTCP XR), you can also configure the device to send the RTCP XR to a specific IP Group using SIP PUBLISH messages.

The PUBLISH message contains the following RTCP XR related header values:

■

From: Telephone extension number of the user

■

To: Telephone extension number of the user

■

Request-URI: IP Group (name) to where RTCP XR is sent

■

Event: "vq-rtcpxr"

■

Content-Type: "application/vq-rtcpxr"

The following is an example of a sent SIP PUBLISH message with RTCP XR and voice metrics:
