Screen Item Description
VOIP Playout Statistics
Playout Buffer Size Displays how much audio can be received from the network before packets are
lost. This is four times bigger than configured packet size. This is a static system
setting.
Nominal Playout Delay Displays how much audio is collected before playout begins. Playout begins at half
the Playout Buffer Size, which is two times the configured packet size. This is a
static system setting.
Average Playout Delay Displays the actual average audio collected before packets are played out. This is
measured over the length of the connection.
Playout Buffer Underrun Displays the number of times that packets were not played because the Playout
Buffer was empty.
NOTE: If VAD is enabled, there are playout buffer underruns whenever there
are no packets being received during silence.
Playout Buffer Overrun Displays the number of packets that were discarded because the Playout Buffer
was full.
Missing Sequence Packet Displays how many audio packets were missed in the sequence.
Replaced Packets Displays how many audio packets were replayed. If a playout underrun occurs, the
latest packet is replayed once; after this, if no more audio packets have been
received, silence is played.
Average Frame Jitter Displays the measure of consistency of packet arrival times. Lower jitter is better.
