This feature supports high definition, three-way conferencing using wideband codecs
(e.g., G.722 and AMR-WB). Therefore, this feature allows conference participants to
experience wideband voice quality. Call conferences can also include narrowband and
wideband participants.

This feature enables the inclusion of call quality of service (QoS) statistics in SIP BYE
and SIP 200 OK responses to BYE, using a proprietary SIP header, X-RTP-Stat. This
proprietary header is enabled using the new parameter, QoSStatistics. By default, this
parameter is disabled.
The X-RTP-Stat header provides the following statistics:
• Number of received and sent voice packets
• Number of received and sent voice octets
• Received packet loss, jitter (in ms), and latency (in ms)
The X-RTP-Stat header includes the following fields:
• PS=<voice packets sent>
• OS=<voice octets sent>
• PR=<voice packets received>
• OR=<voice octets received>
• PL=<receive packet loss>
• JI=<jitter in ms>
• LA=<latency in ms>
