This button leads back to the previous page of
a fixed sequence of pages (used mainly in
wizards).
This button leads back to the page you have been on
before.
This button leads onward to the next page of a
fixed sequence of pages (used mainly in
wizards).
This button confirms an operation you started before.
This button discards the latest, not yet
confirmed entries. This button confirms an operation you chose before.
This is the last button of a fixed sequence of
pages that completes and saves the entries of
the whole sequence. This button discards an operation you chose before.
This button has the same function like the "?"
in the left button bar. It opens the help page
belonging to the currently active QuadroCS
management page.
This button saves the settings modified on the
currently active management page.
This button opens a window where the last inserted IP
addresses are listed. It is a clipboard that helps the
user to make quick selection of an IP address in case it
has been already used in the past, thus to avoid typing
it again. The clipboard can hold up to 10 IP addresses,
a new IP address will replace the oldest one from the
list.
Recurrent Functional Buttons of the GUI
In connection with tables, the following buttons - among others - usually occur:
Functional Button Description
Add Allows adding a new record to the displayed table. A new page will be displayed to enter the new settings.
Edit Allows modifying the settings of the record selected by its checkbox. Normally only one record may be selected. A new
page will be displayed to enter the modified settings.
Delete Deletes the selected entry(s) of a table. A warning message will demand a confirmation before deleting an existing entry.
Select All Selects all table entry(s) for example for further deletion.
Inverse Selection Inverts an existing selection of table entry(s). If no entries are selected, clicking the button will select all records.
Refresh in... May occur in the lower right corner of a page. It displays the number of seconds remaining until the next refresh of the
page and may be used to reload the page manually.
Most of the tables offer the option to sort the entries in ascending or descending order by clicking the headings of the columns. A small arrow beside
the column heading will show the direction of sorting – upward or downward.
The entries of the table can be selected by the assigned checkboxes - one at a time, for the most part - in order to edit or delete them.
Entering a SIP Addresses correctly
Calls over IP are implemented based on Session Initiation Protocol (SIP) on the QuadroCS. When making a call to a destination that is somewhere
on the Internet, SIP address must be given.
SIP addresses have to be specified in one of the following formats:
“display name” <username@ipaddress:port>
“display name” <username@ipaddress>
username@ipaddress:port
username@ipaddress
username
The display name and the port number are optional parameters in the SIP address. If the port is not specified, 5060 will be set up as the default one.
The range of valid ports is between 1024 and 65536.
A flexible structure of wildcards is allowed. In comparison with a wildcard, the “?” character stands for only one unknown digit and the “*” character
stands for any number of any digits.
Particularly the following combinations can be used for your convenience:
- *@ipaddress - any user from the specified SIP server.
- username@* - a specified user from any SIP server.
- *@* - any user from any SIP server.
Please Note: Wildcards are available for caller addresses
only. No wildcard characters are allowed for called party
addresses. To use “*” and “?” themselves (as non wildcard
characters), use “\*” and “\?” correspondingly

Numerous circumstances may cause a certain application on
QuadroCS to flag an event.
The page Event Settings lists all possible applications that
cause QuadroCS to raise events and allows configuration of
notification (action), should one of these events take place.
Each entry in the events table has its checkbox assigned to the
row. By selecting the corresponding checkboxes, operations
such as Edit may be done for one or more events.
Edit opens the page Edit Event Settings to modify the event
action.
Do Nothing - Nothing will happen when the event occurs.
Display Notification - A notification link will be displayed on
the bottom of all pages and a record is added into the Events
table. The notification is executed as the link “Please Check
you pending events!” that leads to the page System Events.
This action also will take place if an action below (Flash LED
or Send Mail) has been selected, even if not selected
explicitly.
Flash LED - the second LED (yellow) will be blinking once a
second and a notification will be displayed on the bottom of all
pages. For some events the LED will start flashing after a brief
delay.
Send Mail causes sending an e-mail with a notification about
the new event and an event description in the mail body to the
e-mail address specified in the Mail Settings page.
Fig. II-18: Event Configuration Settings page
Actions that are not allowed for the selected event (like mail notification if the link is down or the mail server has been misconfigured) are hidden. For
multiple events editing, action which does not fit at least to one of the selected events will be hidden.
If QuadroCS cannot get an IP address from the DHCP server, or cannot register an extension on the SIP or Routing servers, or cannot reach an
NTP server, it raises only one event for the entire period the action has failed, but continues to try. When the required action is finally successful,
QuadroCS raises an appropriate event.

to select the local country time zone. Timezones are specified
by GMT (Greenwich Mean Time) and by specific timezones for
the United States and Canada.
Enable Simple Network Time Protocol Server enables the
SNTP (Simple Network Time Protocol) server on QuadroCS,
thus QuadroCS becomes the timeserver for its LAN.
Enable Simple Network Time Protocol Client enables the
SNTP client on the QuadroCS, thus QuadroCS becomes a client
to an external timeserver. The checkbox enables the following
parameters:
The SNTP Servers table lists all defined NTP Servers.
Add opens an Add NTP Server page where new NTP server
can be defined. The page contains the NTP Server radio
buttons that are used to choose between a manual or a
predefined NTP server.
Manual requires the NTP server’s FQDN (Full Qualified
Domain Name) or its IP address.
Predefined is used to select the NTP server IP address
from the drop down list, where the most common NTP
servers are listed.
Move Up and Move Down functional buttons are used to sort
NTP servers in the order they need to be accessed. If the NTP
server on the first position in the SNTP Servers' table does not
answer, the NTP server on the next position then will try to be
reached.
Please Note: Add another NTP server to the list if you feel
defined NTP servers are not functional, i.e., the QuadroCS's
date/time is not being automatically updated.
Polling Interval indicates the time interval for the periodical
synchronization between timeserver and QuadroCS. It counts in
hours.

Networking Tools
The Networking Tools provide the capability to check the Internet connection.
Ping sends four ICMP (Internet Control Message Protocol) requests with a default size of 64 bytes to the destination (IP address or host name)
specified in the text field Ping Target. The response times are logged, and the round trip time (the time the packet needs from being sent until being
received again) is measured. The results are displayed in the lower area of the page: The minimal and maximal round trip time and its average, the
percentage of lost and of received frames.
Traceroute checks the Internet connection by triggering the routers (hops) that are passed to reach the destination specified in the text field
Traceroute Target.Trace routing gives feedback on the routers passed by packets on the way toward the destination and the round trip delay of
packets to these routers.
Attention: Traceroute is not possible if a high security Firewall has been enabled (see chapter Firewall).
For the purpose of tracerouting several IP packets are sent out. UDP (User Datagram Protocol) is used to send packets and ICMP (Internet Control

Diagnostics
The System Diagnostic page gives a possibility to run Network
and WAN protocol diagnostics, to verify QuadroCS's connectivity
and to download all system logs for possible problems recovery.
The Start Detecting WAN Protocol button is used to initiate WAN
diagnostics that will detect the WAN IP configuration: static or
through DHCP server. For static WAN IP configuration, gateway
availability is checked. When acting as a client, DHCP server’s
accessibilities are being verified.
The Start Network Diagnostics button is used to initiate network
diagnostics, i.e., to check the WAN link and IP configuration, to
verify gateway, DNS primary and secondary (if configured) servers'
accessibilities.
The field below will display the diagnostics results and the
connectivity conditions. The system should be reconfigured if
problems occur during the diagnostics.
The Reboot this Device button is used to reboot the QuadroCS.
Please note that the session with the QuadroCS will be closed, i.e.,
the QuadroCS GUI should be newly opened and a new login will
be required afterward.
The Download system logs button is used to download all logs to
the local PC as a *.tar archive file. These logs can then be used by
the Epygi Technical Support Office to determine the problem that
had occurred on your QuadroCS.

Conferences
The Conference Management page is divided into two pages: All Conferences page where new conferences can be arranged and the Active
Conferences page to preview or to terminate the active conferences.
The Active Conferences page includes a table with all active conferences on the QuadroCS and their parameters (Conference ID, Subject,
Description, Status, Recording Space and Codecs). This page allows termination of the selected conference or monitoring of the conference
progress.
The All Conferences page includes a table that lists all created
conferences and their parameters. The table displays the
Conference ID, the conference Subject, a Description, the
actual Status, the Recording Space and the corresponding
Codecs. Each column heading in the table is created as a link.
By clicking on the column heading, the table will be sorted by
the selected column. Each record in the table has a checkbox
assigned to the row. The checkbox is used to edit, activate,
duplicate and delete the corresponding record.
Please Note: There is a 40 conference-rooms limitation on the
QuadroCS, but the amount of all participants cannot exceed 25
at the same time.
Each conference in the Conferences table has its specific voice
Codecs configured, which can be accessed and modified by
clicking on the link in the Codecs column of the corresponding
conference.
Clicking on the corresponding conference ID will link you to the
Moderator’s page where the conference properties can be
configured.
Clicking on the conference status link (which appears when
conference state is Active or Waiting), displays a page with
information on the conference. This page displays a list of
conference participants and gives an option of dropping a
participant from the conference or inviting new participants. It
also allows the moderator to start/stop/resume/pause the
conference recording and to terminate the conference. Fig. II-31: Conference Management page
