Local Extensions
The embedded PBX functionality of OxyGEN miniOffice allows each FXS port and, when available,
each DECT handset, Internal (NT) ISDN interface and local VoIP phone (optional features) to have its
own internal phone number. The
Extensions
sub-menu allows the configuration of these internal phone
numbers (local extensions).
Entering the sub-menu, a list of all configured local extensions with their current status is displayed.
Figure 10.6: List of Extensions
You can Edit and Delete configured extensions by clicking on the icons
and
respectively of
Action
column.
In order to add a new local extension, click
Add New
and the following page appears:
Each local extension is uniquely described by its internal
Number
.
No extensions can share the
same internal
Number
. After entering the
Number
of the local extension, select its type using the
Port
drop-down menu. Available options are the different local voice interfaces of the OxyGEN miniOffice
or
SIP Phone
for an external IP phone. In the latter case, a
MAC Address
value is required in order
to uniquely identify the IP phone device (use a dummy/virtual MAC value in case of PC softphones)
and the
Credentials
(
Username
and
Password
) for the registration of the external VoIP client on the
embedded PBX of the OxyGEN miniOffice.
The rest of the parameters, common for each type of local extension, are:
Name
: the name assigned to the local extension and transmitted in outgoing calls as the calling
name.

External line
: the VoIP service account used for external calls originating from the configured local
extension (refer to sections

Apart from the main extension parameters, this page allows also the configuration of the status of
Supplementary Services
:
Accept DDI external calls
: a checkbox indicating if the configured number is a strictly local
extension number or if incoming calls for the specific number should also be accepted on the
external voice lines.
Anonymous Call Rejection
:
a checkbox indicating whether the configured local extension
accepts or rejects incoming call attempts without CLIP information (i.e. anonymous calls).
Call Waiting
: a checkbox controling the activation/deactivation of the Call Waiting supplementary
service (option available only on local voice interfaces).

DECT Station
The OxyGEN miniOffice is optionally equipped with an embedded DECT base-station. This feature allows
the addition of up to 6 DECT handsets, with each of these handsets handled as a totally independent
device.
This means that each handset has its own local extension number and is independently
configured, like any FXS port or optional local VoIP phone, using the
Local Extensions
configuration
sub-menu (see page 111).
Before configuring, however, a DECT handset as a local extension, it must first be added to the list of
known or "paired" handsets. This is performed using the
DECT Station
configuration sub-menu.
Figure 10.8: List of DECT Handsets
The table on the top of the page lists all configured DECT handsets. You can Delete configured
DECT handsets by clicking on the icon
of
Action
column.
In order to activate "pairing mode" on the OxyGEN miniOffice, enter the 4-digit
PIN
value and press
the
Start
button. The "pairing mode" is deactivated either automatically after 60 seconds or by pressing
the
Stop
button.
Note
The embedded DECT base-station of OxyGEN miniOffice is interoperable with handsets
conforming to the GAP (Generic Access Profile) protocol.
Note
Please refer to the documentation of your GAP-compatible DECT handset in order to
identify the procedure of activating "pairing-mode" on the handset.

ISDN Interfaces
This configuration page allows the control of the optional ISDN voice interfaces of the OxyGEN miniOffice.
Figure 10.9: ISDN Voice Interfaces
All ISDN interfaces are programmable and can be configured to operate either in
External (TE)
or
Internal (NT)
mode.
External mode must be selected in order to connect the interface to an ISDN
Network Termination Unit (NT) and the public ISDN network. On the other hand, Internal mode must be
selected in order to connect to an ISDN PBX replacing the ISDN Network Termination Unit and the public
ISDN network with the broadband VoIP network.
WARNING
Although programmable, you will need a different type of cable for each mode of
operation. When operating in
Internal (NT)
mode, use a straight-through cable for the
connection, whereas for
External (TE)
mode, an ISDN crossover cable is required. Please
refer to
Appendix F
on page 205 for details about the pinout of both cables.
By clicking on the Edit icon
next to each ISDN interface, a page like the following appears:
Using this page, it is possible to configure the parameters related to the operation of the specific
ISDN interface:
Mode
of operation. This parameter controls the operation of the interface either in External (TE) or
Internal (NT) mode.
Connection type
. This drop-down list allows to select between Point-to-Point (PTP) and Point-to-
Multipoint (PTMP) for ISDN DDI and MSN connections respectively.
Early media
operation. This checkbox controls if the interface enables transmission and reception
of voice stream before the call is connected (e.g. for in-band notifications or tones).

Hold L1
and
Hold L2
functionality. These checkboxes control if the ISDN Layers 1 and 2 respectively
are going to be constantly kept activated or if they are going to be dynamically brought up and
down. Usually, both checkboxes should be selected for Point-to-Point (PTP) type of connections
(ISDN DDI) and unselected for Point-to-Multipoint (PTMP) type of connections (ISDN MSN).
External line
for outgoing calls. This drop-down list controls, for Internal (NT) interfaces only, which
VoIP service account is used for outgoing external calls (please refer to sections
External Lines
on
page 107 and
VoIP Trunking
on page 110).
After selecting the mode and other parameters for each ISDN interface, the last step is to control
if all interfaces are going to operate like totally independent interfaces or if they are going to operate
in group-mode. In the former case, every ISDN interface is treated as a totally separate entity in all
voice-related configuration pages, whereas in the latter all External (TE) interfaces form one group (
ISDN
TE
) and all Internal (NT) another (
ISDN NT
) (for example, see the
Route calls to
parameter in section
External Lines
on page 107 or the
Outgoing
and
Fallback
drop-down lists in section
Dial Plan
on page
117).
Selection between these two modes of interface behavior is performed, individually for the External
(TE) and the Internal (NT) interfaces, using the
Interface hunting
drop-down list. Value None corresponds
to independent interfaces, whereas the other options correspond to grouped operation with different
interface hunting modes. Specifically:
Linear distributes voice calls following a linear schedule.
Round-Robin distributes voice calls following a round-robin schedule.
Parallel sends calls simultaneously to all grouped ISDN interfaces.
None treats each ISDN interface separately.
