Diagnostics

•Silence suppression: Number of silence suppression activation objects found in the RTP stream received. A silence suppression activation object is defined as a period of silence when no encoded voice signals were transmitted by the sender.

•Count of good packets: Total amount of good packets.

•Maximum jitter: Maximum jitter (in ms) found during the report interval.

•Maximum inter-arrival jitter: Maximum of the interarrival jitter values (in ms). The interar- rival jitter is the smoothed absolute value of the jitter measurements. It is calculated con- tinuously. For details about the calulation, see RFC 3550.

•Periods jitter threshold exceeded: Number of observation intervals in which the thresh- old for maximum jitter was exceeded.

•Round trip delay: Average value of delay calculated for each RTCP packet. The first value is available after about 15 sec.

•Round trip delay threshold exceeded: Set to "true" if the average round trip delay thresh- old value was exceeded in the report interval.

•Count of lost packets: Number of packets lost in the course of speech decoding.

•Count of discarded packets: Number of the packets discarded without transferring the contents.

•Periods of lost packets: Number of observation intervals in which the threshold for lost packets was exceeded.

•Consecutive packet loss (CPL): List of sequences consecutive packets that were all lost, grouped according to the amount of packets per sequence. The first number in the list counts single lost packets, the second number counts sequences of two lost packets, and so on. The last number counts sequences of more than 10 lost packets.

•Periods of consecutive lost packets: Number of observation intervals in which the threshold for consecutive lost packets was exceeded.

•Consecutive good packets (CGP): List of sequences consecutive packets that were all processed, grouped according to the amount of packets per sequence. The first number in the list counts single good packets, the second number counts sequences of two good packets, and so on. The last number counts sequences of more than 10 good packets. All values are reset to 0 after an interval without packet loss.

•Periods of consecutive good packets: Number of intervals in which the count of lost packets went below the threshold.

•Count of jitter buffer overruns: Number of packets rejected because the jitter buffer was full.

•Count of jitter buffer under-runs: Increased by one whenever the decoder requests new information on decoding and finds an empty jitter buffer.

•Codec change on the fly: The value is 1, if there has been a codec or SSRC change dur- ing the observation period, and 0, if there has been no change.

•Periods with at least one threshold exceeded: Number of observation intervals with at least one threshold exceedance. If there is no data, the value is 255. The threshold values included are:
