ISDN BRI Layer 3
statistics:
Active Calls
shows the number of currently active calls in the selected trunk.
Outgoing Calls
shows the number of all outgoing calls in the selected trunk.
Incoming Calls
shows the number of all incoming calls in the selected trunk.
ISDN trunk statistics are not displayed on this page at first, but the page is automatically refreshed every 10 minutes. Statistics collected from that
time, as well as the last resetting of the counter, will be displayed there.
System Uptime

Current System Time
and
Last Time Cleared

ISDN statistics has been cleared) are displayed at the bottom of the page.

Gain Control
The Gain Control settings are used to define transmit and receive gains.
•
For ISDN trunks
Transmit Gain
defines the level of voice
transmitted by Quadro to the PSTN network and
Receive Gain
defines the volume of voice received by Quadro from the PSTN
network.
•
For Voice Mail the
Recording Gain
defines the volume of the
phone microphone upon playing voice mails or system messages
and the
Playback Gain
defines the phone speaker volume upon
playing voice mails or system messages.
The
Gain Control
page consists of the
Transmit Gain
and
Receive
Gain
drop down lists for each line. They contain the allowed gain
values, which can be set by the administrator for every line.
Please Note:
If gain control is configured incorrectly, DTMF digits may
not be recognized properly. The gain control settings depend solely on
the board location (country) and the phone type.
The
Restore Default Gains
button reloads 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
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
table on both devices, the SIP calls will be routed from Quadro1 to
Quadro2 and vice versa.
