Streaming Statistics
Ta b l e 6-7 Streaming Statistics Area Items
Item Description
Remote Address IP address and UDP port of the destination of the stream.
Local Address IP address and UDP port of the phone.
Start Time Internal time stamp indicating when Cisco Unified Communications Manager requested
that the phone start transmitting packets.
Stream Status Indication of whether streaming is active or not.
Host Name Unique, fixed name that is automatically assigned to the phone based on its MAC address.
Sender Packets Total number of RTP data packets transmitted by the phone since starting this connection.
The value is 0 if the connection is set to receive only mode.
Sender Octets Total number of payload octets transmitted in RTP data packets by the phone since starting
this connection. The value is 0 if the connection is set to receive only mode.
Sender Codec Type of audio encoding used for the transmitted stream.
Sender Reports Sent
1
Number of times the RTCP Sender Report have been sent.
Sender Report Time Sent
1
Internal time stamp indication when the last RTCP Sender Report was sent.
Rcvr Lost Packets Total number of RTP data packets that have been lost since starting receiving data on this
connection. Defined as the number of expected packets less the number of packets actually
received, where the number of received packets includes any that are late or duplicate. The
value displays as 0 if the connection was set to send-only mode.
Avg Jitter Estimate of mean deviation of the RTP data packet inter-arrival time, measured in
milliseconds. The value displays as 0 if the connection was set to send-only mode.
Rcvr Codec Type of audio encoding used for the received stream.
Rcvr Reports Sent
1
Number of times the RTCP Receiver Reports have been sent.
Rcvr Report Time Sent
1
Internal time stamp indication when a RTCP Receiver Report was sent.
Rcvr Packets Total number of RTP data packets received by the phone since starting receiving data on
this connection. Includes packets received from different sources if this is a multicast call.
The value displays as 0 if the connection was set to send-only mode.
Rcvr Octets Total number of payload octets received in RTP data packets by the device since starting
reception on the connection. Includes packets received from different sources if this is a
multicast call. The value displays as 0 if the connection was set to send-only mode.
Latency
1
Estimate of the network latency, expressed in milliseconds. Represents a running average
of the round-trip delay, measured when RTCP receiver report blocks are received.
Max Jitter Maximum value of instantaneous jitter, in milliseconds.
Sender Size RTP packet size, in milliseconds, for the transmitted stream.
Sender Reports Received
1
Number of times RTCP Sender Reports have been received.
Sender Report Time
Received
1
Last time at which an RTCP Sender Report was received.
Rcvr Size RTP packet size, in milliseconds, for the received stream.
Rcvr Discarded RTP packets received from network but discarded from jitter buffers.
Rcvr Reports Received
1
Number of times RTCP Receiver Reports have been received.
Rcvr Report Time Received
1
Last time at which an RTCP Receiver Report was received.
