PSTN Lines Sharing
PSTN Lines Sharing page is used to configure QuadroISDN to act as an ISDN expansion device for the remote Quadro IP PBX, i.e. to share its
ISDN trunks to the master Quadro IP PBX. This provides Quadro IP PBX a possibility to call not only through local ISDN lines but also through
available shared ISDN lines on the QuadroISDN.
When sharing mode is enabled, the ISDN Settings page becomes read-only on QuadroISDN and corresponding routing patterns are automatically
created in the
Call Routing table.
• The configuration of all ISDN trunks on the QuadroISDN will become transparent to Quadro IP PBX upon enabling the sharing mode.
• Independent of the configuration on the QuadroISDN, the incoming calls on all shared ISDN trunk will be automatically routed to the
default Auto Attendant (00) once ISDN sharing is activated. Occasionally, routed destinations can be then changed on Quadro IP
PBX.
• Any changes applied to the configuration of shared ISDN lines on the Quadro IP PBX will be automatically reflected in the ISDN
Settings page and Call Routing table on the QuadroISDN.
PSTN Lines Sharing page consists of the following
components:
The Provide PSTN lines for master device checkbox is used
to share the existing ISDN lines to the remote Quadro.
Username and Password text fields are used to enter the
identification parameters for the authentication on the remote
Quadro IP PBX. In its turn, these authentication settings should
be added in the Authorization Parameters table on the master
Quadro IP PBX.
Master device IP text field requires the IP address of the
master Quadro current ISDN trunks will be shared for.
Master device port text field requires the port number of the
master Quadro current ISDN trunks will be shared for.
Registration State and Registration Date/Time fields indicate
read-only information about the last successful registration on
the master Quadro (i.e. when authentication was successful), its
state and the registration date/time.

Gain Control
The Gain Control settings are used to define transmit and
receive gains. For ISDN lines, Transmit Gain defines the level
of voice transmitted from Quadro to the PSTN network and
Receive Gain defines the volume of voice received by Quadro
from the PSTN network.
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.
Please Note: If the gain control has been configured incorrectly,
DTMF digits may not be properly recognized. Gain control
settings are strictly dependent on the location (country) of
Quadro and the phone type.
The Restore Default Gains button restores the default values.

Call Routing
The Call Routing service simplifies the calling procedure for Quadro users, i.e., different types of calls (internal, SIP, ISDN or IP-PSTN) can be
placed in the same way. SIP registration is not needed for extensions to make routing calls.
