OxyGEN
mini
Office
Administrator’s Guide
(either voice interfaces or local VoIP numbers) are listed in the
List of Extensions
table.
Using the
arrow-buttons, the desired local extensions can be moved to and back from the
Selected Extensions
table. The result of this procedure is that, whenever an incoming call for the number(s) of this external
line is received by the OxyGEN miniOffice, the number is going to be compared with the list of
Local
Extensions
and, if no match is found, the
Selected Extensions
are going to ring.
ISDN
In the case of
ISDN
external lines, the first thing to configure is the ISDN mode of operation:
MSN
(Multiple
Subscriber Numbers) or
DDI
(Direct Dial In). In both of these modes, multiple numbers can be assigned
to the line. The most important functionality difference, however, is that Multiple Subscriber Numbers are
different (not necessarily consecutive) numbers over the same, single ISDN line, in a point-to-multipoint
mode of operation, whereas with Direct Dial In multiple, consecutive numbers are applied to one or
more ISDN lines, but with a point-to-point mode of operation.
Subscription to the MSN and DDI services is mutually exclusive. You have to ask your provider for the
mode of operation and the numbers assigned to your external ISDN line(s).
The rest of the configuration parameters are similar to the VoIP account settings:
you have to
configure a single (in case of MSN) or a whole range of numbers (in case of DDI), for which the incoming
calls are going to be handled by the OxyGEN miniOffice, optionally apply any number tranformations
(Significant digits and Add prefix) and then select the local extension to which the corresponding calls
are going to be directed.
Note
The ISDN parameters appear only when at least one ISDN voice interface is configured
to operate in
External (TE)
mode. Please refer to section
ISDN Interfaces
on page 114
for a description of the corresponding configuration.
Note
The operation of your external ISDN line in
MSN
or
DDI
mode depends on your ISDN
telephony service provider.
