For Audio Lines (This option is available only for QuadroM8L/26x/12Li/26xi):
Transmit Gain (Line Out) defines the level of voice transmitted from Quadro to the Audio Line Out port.
Receive Gain (Line In) defines the volume of voice received by Quadro from the Audio Line In port.
The Gain Control page offers Transmit Gain and Receive Gain drop down lists for each line that contains allowed gain values, which can be set up
by the administrator for every line.
The Restore Default Gains button restores the default values.
SIP Tunnel Settings
The SIP Tunneling service is used to build a tunnel between Quadros and to use that tunnel for routing the SIP calls through the remote Quadros.
When this service is enabled, slave Quadros should be registered on the master Quadro with the corresponding username/password. With the
appropriate configuration done on the master Quadro, the master device can use the slave Quadros for routing the SIP calls through them and
accessing peers located behind the slave Quadro or recognized by it. This enables the master Quadro to locate the slave, even when the network
settings, like IP address, SIP port and other settings are changed on the slave Quadro.
When the SIP Tunneling service is enabled, virtual tunnels between the master and its slaves are created. A possibility to use the created SIP
tunnels will be automatically enabled in the
Call Routing table.
Optionally, a SIP tunnel can be mutually established on two Quadros allowing to route SIP calls back and forth. A Quadro can be at the same time
configured both as a slave and as a master to the same remote device, i.e. the slave Quadro can act as a master for the master device it is
registered on. For example, the Quadro1 can act as a slave for the Quadro2. In its turn, the Quadro2 can act as a slave for the Quadro1. With this
configuration and the corresponding routing rules added in the
Call Routing table on both devices, the SIP calls will be routed from Quadro1 to
Quadro2 and vice versa.
The SIP Tunnel Settings page is used to enable the Quadro as
a slave or master device
for SIP tunneling. The page consists of
the following components:
The Enable Tunnels to Slave Devices checkbox enables the
Quadro as a master device and allows you to configure the SIP
tunnels to the slave Quadros. When this checkbox is enabled
the Tunnels to Slave Devices table needs to be configured.
The link Tunnels to Slave Devices moves you to the page
where a list of slave devices needs to be defined.
Fig. II-215: SIP Tunnel Settings page
The Tunnels to Slave Devices page consists of a table where
slave devices are listed with the corresponding authentication
parameters.
Add functional button leads to the Add Entry page where a new
slave device parameters needs to be provided.
The Add Entry page consists of the following components:
The SIP Tunnel Name text field requires the tunnel name for
the corresponding connection. System suggests you to start the
SIP tunnel name with the “SIP_Tunnel_” words, according to the
automatic prefix used for the SIP tunnels on the Quadro,
however this is not mandatory.
The User Name text field requires the authentication user
name. The field in front of this text field displays the default non-
editable prefix for SIP tunnels: “SIPTunnel_”.
The Password text field requires the authentication password.
Please Note: The User Name and Password should match
both on master and slave Quadros for the successful SIP tunnel
establishment.
The Symmetric NAT
checkbox should be selected when the
slave Quadro is located behind the symmetrical NAT.
