Quadro Baseline
Attached Line lists all free lines to where an extension may be
attached.
Please Note: Extensions cannot be detached from the line if the
SIP Remote Extension service is enabled on it. To detach the
extension from the line, disable the SIP Remote Extension
service on the extension first.
Allow Call Relay enables the current extension to be used to access the Call Relay service in the Quadro's Auto Attendant. It is recommended to
define a proper and non-empty password when enabling this feature in order to protect the Call Relay service from an unauthenticated access.
When External Call Policy checkbox is enabled, all incoming IP calls to the corresponding extension will be handled by the external Policy Server.
The Percentage of System Memory drop down list allows you to select the space for the extension's voice mails and uploaded/recorded greetings
and blocking messages. The maximum value in the drop down list is equal to the maximum available space for voice messages on Quadro. When
editing an existing extension and decreasing the voice mailbox size, the system will check the present amount of voice mails in the mailbox of the
extension. If the memory required for these voice mails exceeds the size entered, the system will suggest either to remove all voice messages from
the extension's voice mailbox or to select a larger size so that the existing voice messages can be stored in the mailbox.
2. SIP Settings
This group is used to configure extension's SIP registration
settings and consists of the following components:
User Name requires a user name for the extension registration
on the SIP server. The registration user name needs to be
unique on the SIP server and it is displayed on the called phone
when performing an IP call.
Password indicates the password for the extension registration
on a SIP server.
Registration Password is used to confirm the password. If the
entered password does not correspond to the one entered in the
Password field, the error message "The passwords do not
match. Please try again" will appear.
SIP Server indicates the host address of the SIP server. The
field is not limited regarding symbol usage or length. It can be
either an IP address such as 192.168.0.26 or a host address
such as sip.epygi.com.
SIP Port indicates the host port number to connect to the SIP server. The SIP server port may only contain digit values, otherwise the error message
"SIP Server Port is incorrect" will be displayed when applying the extension settings. If the SIP server port is not specified, Quadro will access the
SIP server through the default port 5060.
Registration on SIP Server enables the SIP server registration option. If the extension has already been registered on an SIP server, its IP address
will be displayed in brackets.
3. SIP Advanced Settings
This group is used to configure advanced SIP settings (Outbound Proxy, Secondary SIP Server and Outbound Proxy for the Secondary SIP Server
settings and to define other SIP server specific settings).
The SIP Outbound proxy is an SIP server where all the SIP requests and other SIP messages are transferred. Some SIP servers use an outbound
proxy server to escape restrictions of NAT. For example, Free World Dialup service uses an Outbound Proxy server. If an Outbound proxy is
specified for an extension, all SIP calls originating from that extension are made through that outbound proxy, i.e., all requests are sent to that
outbound proxy, even those made by Speed Calling.
The Secondary SIP Server acts as an alternative SIP registration server when the primary SIP Registration Server is inaccessible. If the connection
with the primary SIP server fails, Quadro will automatically start sending SIP messages to the Secondary SIP Server. It will switch back to the
primary SIP server as soon as the connection is reestablished.
