Rx Maximum Delay = max V(i) / 8
RX Delay Increase Count – indicates the number of times the delay in jitter buffer is increased during the call.
RX Delay Decrease Count - indicates the number of times the delay in jitter buffer is decreased during the call.
Please Note: RTP Statistics is logged only when at least one of the call endpoints is located on the Quadro. For example, it will not be logged when:
•
calls incoming from or addressed to the IP lines or remote extension,
•
calls from an external user are routed to another external user through Quadro’s routing rules.
In the first case, RTP statistics will be logged if remote extension or IP line user is calling locally to the Quadro’s extension or auto attendant.
The Configure Call Quality Event Notification link leads to the Configure Call Quality Event Notification page where call quality control
notification specifics can be configured.
From the Configure Call Quality Event Notification page you may configure event notification policy when the call quality is lower than the allowed
level.
This page consists of a Notify checkbox, which enables the call
quality monitoring mechanism for the corresponding event
notifications, and a
Call Quality less than drop down list where the
least satisfactory call quality should be selected. When a call with the
quality less than the level selected here is registered on the Quadro,
an event notification will appear. When the
Notify checkbox is
disabled, no Call Quality events will occur on the Quadro.
Please Note: The ways of notification for the Call Quality events
should be configured from the Events page.

The Configure System Events link leads to the Events page where the methods of notification for each system event can be configured.
FAX Statistics
The FAX statistics page is accessed from the Call Statistics page by
clicking on the FAX link in the Details column for the calls that
contain T.38 FAX transmission.
The FAX statistics page provides information about received and
transmitted packets, lost, bad and duplicated packets. This statistics
refers only to the T.38 FAX transmission. The FAX statistics is not
available for the FAX transmitted with other protocols.

SIP Settings
The SIP Settings provide information on the SIP receive UDP and TCP ports and allows you to select DNS server configurations for SIP and the SIP
timers scheme.
The UDP Port indicates the SIP UDP (User Datagram Protocol)
receive port number. By default 5060 is selected and used. The
SIP UDP port cannot be in the selected RTP/RTCP port range for
IP lines (see
RTP Settings ), otherwise the “Mapped port for SIP
shouldn’t be in RTP port range” error message appears.
The TCP Port indicates the SIP TCP (Transmission Control
Protocol) receive port number. By default, 5060 is selected and
used.
Please Note: Quadro will not use TCP protocol as a transport for
SIP messages if the TCP Port field is left empty.
Enable Session Timer enables advanced mechanisms for
connection activity checking. This option allows both user agents
and proxies to determine if the SIP session is still active.
The DNS server for SIP radio button group allows you to choose
between regular DNS servers configured in the DNS Settings page
and specific DNS servers for SIP traffic.
•
Use default is used to apply regular DNS servers for SIP
traffic.
•
Specific is used to enable SIP specific DNS servers. For this
selection, both primary and secondary SIP DNS servers
should be defined in the
SIP DNS 1 and SIP DNS 2 text
fields. At the least, a primary DNS server should be inserted.
