UserID
requires an identification parameter to reach the SIP server. It should have been provided by the SIP service provider and can be requested
for some SIP servers only, for others, the field should be left empty.
Send Keep-alive Messages to Proxy
enables the SIP registration server accessibility verification mechanism.
Timeout
indicates the timeout
between two attempts of SIP registration server accessibility verification. If no reply is received from the primary SIP server within this timeout, the
secondary SIP server will be contacted. When the primary SIP server recovers, SIP packets will be sent to it once again.
A group of
Host address
and
Port
text fields respectively require the host address (IP address or the host name), the port number of the
Outbound
Proxy
,
Secondary SIP Server
and the
Outbound Proxy for the Secondary SIP Server
. These settings are provided by the SIP servers’ providers
and are used by Quadro to reach the selected SIP servers.
VoIP Carrier Wizard – Page 3
contains VoIP Carrier access
code selection components:
Access Code
text field requires a digit combination by dialing
which the corresponding VoIP Carrier will be reached.
Route Incoming Calls To
drop down list allows to select an
extension (or Auto Attendant) on the Quadro where incoming
calls from the configured VoIP Carrier should be routed to.
Failover to PSTN
checkbox selection will route the call to
PSTN through local FXO line in case if VoIP Carrier is not
available. When this checkbox is selected, an additional entry
will be added to the
Local Call Routing
table maintaining digit
transmission to local PSTN when IP call towards the
configured VoIP Carrier cannot be established.
Please Note:
Warning message will inform that the defined
Access Code
already exists in the
Local Call Routing
causes a conflict with entries already in the
Local Call Routing
table. In this case, when proceeding the
VoIP Carrier Wizard
,
existing entry in the
Local Call Routing
table will be
automatically overwritten by the new settings.

RADIUS Client Settings
The
RADIUS
(Remote Authentication Dial In User Service) specifies the RADIUS protocol used for authentication and authorization, to differentiate,
to secure and to account for the users. The RADIUS Server gives an extra possibility for caller from/through Quadro to pass authentication to be able
to dial the specific number.
When RADIUS client is enabled on the Quadro, any caller that dials routing pattern with
Authentication&Accounting
option selected (see
Local
table), will primarily pass authentication locally, through
Local AAA Table
, and if local authentication failed, will pass additional
authentication on the RADIUS Server. This can be accomplished by caller’s number automatic detection or a customizable login prompt, where caller
is expected to enter username and password.
Transactions between the client and the RADIUS server are authenticated through the use of a shared Secret Key, which is never sent over the
network. In addition, any user passwords are sent encrypted between the client and RADIUS server, to eliminate the possibility that someone
snooping on an insecure network could determine a user's password. If no response from the RADIUS Server is returned after Receive Timeout
expires, the request is resent a number of times, defined in the Retry Count list. The client also can forward requests to an alternate server or servers
if the primary server is down or unreachable. An alternate server can be used after a number of failed tries to the primary server.
Once the RADIUS server receives the request, it determines if the sending client is valid. A request from a client that the RADIUS server does not
have a shared secret must be silently discarded. If the client is valid, the RADIUS server consults a database of users to find the user whose name
matches the request. The user entry in the database contains a list of requirements (username, password, etc.) that must be met to give access to
the user. If all conditions are met, the user gets access to the Quadro Network.
The
RADIUS Client Settings
page contains the
Enable RADIUS Client
checkbox that enables RADIUS client on the Quadro. The other RADIUS
Client settings are divided into three groups:
