Max RTP ICMP Err
RTCP Tx Interval
No UDP Checksum
Stats In BYE
Number of successive ICMP errors allowed when
transmitting RTP packets to the peer before the WRP400
terminates the call. If value is set to 0, the WRP400 ignores
the limit on ICMP errors.
The default is 0.
Interval for sending out RTCP sender reports on an active
connection. It can range from 0 to 255 seconds. During an
active connection, the WRP400 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/wrp400-1.0.31(b)). The NTP timestamp used in the
SR is a snapshot of the WRP400's local time, not the time
reported by an NTP server. If the WRP400 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 the WRP400 Configuration Utility.
The default is 0.
Select yes if you want the WRP400 to calculate the UDP
header checksum for SIP messages. Otherwise, select no.
The default is no.
Determines whether the WRP400 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.
