Sdp Payload Types Section - Linksys RTP300 - Broadband Router With 2 Phone Ports Administration Manual

RTCP Tx Interval 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 Linksys/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.
No UDP Checksum Select yes if you want the ATA device to calculate the UDP header checksum
for SIP messages. Otherwise, select no.
The default is no.
Stats In BYE 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.
