Stats In BYE
Interval for sending out RTCP sender reports on an active
connection. It can range from 0 to 255 seconds. During an
active connection, the ATA device can be programmed to
send out compound RTCP packet on the connection. Each
compound RTP packet except the last one contains a SR
(Sender Report) and a SDES.(Source Description). The last
RTCP packet contains an additional BYE packet. Each SR
except the last one contains exactly 1 RR (Receiver
Report); the last SR carries no RR. The SDES contains
CNAME, NAME, and TOOL identifiers. The CNAME is set to
<User ID>@<Proxy>, NAME is set to <Display Name> (or
Anonymous if user blocks caller ID), and TOOL is set to the
Vendor/Hardware-platform-software-version (such as
Cisco/ATA device-1.0.31(b)). The NTP timestamp used in
the SR is a snapshot of the ATA device’s local time, not the
time reported by an NTP server. If the ATA device receives
a RR from the peer, it attempts to compute the round trip
delay and show it as the <Call Round Trip Delay> value
(ms) in the Info section of ATA device web page.
The default is 0.
header checksum for SIP messages. Otherwise, select no.
The default is no.
Determines whether the ATA device includes the P-RTP-
Stat header or response to a BYE message. The header
contains the RTP statistics of the current call. Select yes or
no from the drop-down menu. The format of the P-RTP-Stat
header is:
P-RTP-State: PS=<packets sent>,OS=<octets
sent>,PR=<packets received>,OR=<octets
received>,PL=<packets lost>,JI=<jitter in ms>,LA=<delay
in ms>,DU=<call duration in
s>,EN=<encoder>,DE=<decoder>.
The default is no.
