Preface
Thank you for your confidence in us!
LANCOM Business-VoIP-Routers offer innovative all-round solutions that
integrate data and voice applications with basic PBX functions in a single
compact device. The range of interfaces available enables a LANCOM
Business-VoIP-Router to provide connections for ISDN or analog telephones,
and fax machines. The LAN interfaces allow additional SIP telephones or
softphones in the internal network to be connected up as well.
LANCOM Routers provide PBX functions via Voice over IP, making them a
technically mature alternative to conventional ISDN PBXs. They are ideal for
smaller companies, branch offices and telecommuters. Even if the Internet
connection should fail, calls can still be made to the PSTN via an ISDN or
analog interface. What's more, internal SIP users can be called from landlines
by using standard telephone numbers. In this way, home offices and smaller
sites can be cost-effectively equipped with a standardized telephony system
based on SIP.
Model variants
This manual applies for all LANCOM Business-VoIP-Routers (1722, 1723,
1724 and 1823 VoIP).

1Introduction
LANCOM Business-VoIP-Routers can provide small companies or subsidiaries
with all of the functions of a classical private branch exchange (PBX).
Connection of telephones and fax machines (ISDN or analog)
Internal telephone calls between all connected subscribers
Telephony functions such as call hold, swap, connect or call transfer
(redirect calls)
Hunt group function with flexible call distribution and cascading of hunt
groups
Along with these functions familiar from ISDN PBXs, the LANCOM

3 Configuring the VoIP functions
Prerequisites for the configuration of the VoIP functions in a LANCOM
Business-VoIP-Router are suitable basic settings and a functional Internet
connection. To this end, please ensure that you use the Wizards in LANconfig
to configure the basic settings, the Internet connection and the security
settings before you configure VoIP.
3.1 This is how you draw up a dialing plan
The planning of telephone infrastructure can be greatly helped by drawing up
precise details on the connections, their telephone numbers and any hunt
groups that may be required, as this information is important to the
configuration. To help you with this, you should fill out the table (below)
before you begin with the configuration.
3.1.1 PBX users
Users are all of the devices for tele(phonic) communications, i.e. ISDN and
analog telephones, SIP telephones, computers with software telephones, or
fax machines. As a rule, every user receives its own internal telephone number
that can be accessed from within the company. If necessary, multiple devices
can share the same telephone number (’Multi-login’ →Page 36).
Use a uniform number format so as to avoid problems with the
processing of internal telephone numbers, e.g. use two- or three-digit
numbers only.
The external telephone number is used to reach the user from the PSTN (public
services telephone network). At ISDN point-to-multipoint connections these
numbers are referred to as MSNs (Multiple Subscriber Numbers). At an ISDN
point-to-point connection you enter the direct-access telephone number
(DDI, Direct Dialing-In). You should then enter the type of device and
connection.
Please observe the maximum number of users permissible for your
LANCOM model.
The following table provides an overview of the allocation of users to hunt
groups (’Hunt groups’ →Page 16), which suffices for many applications.

3.1.2 Hunt groups
A hunt group collects two or more users who/which should be reached under
a single telephone number. For example, a hunt group can be used to dial all
of the staff within a department (’Hunt groups with call distribution’
→Page 34). Apart from its members, a hunt group can also be set with the
manner of call distribution, a time period after which (unanswered) calls are
forwarded, and a number as the target for call forwarding.
3.2 This is how you configure the LANCOM Business-
VoIP-Router as a PBX
Under LANconfig, start the setup wizard for configuring the VoIP Call
Manager.

Under 'Lines', activate the exchange line over which you telephone via the
PSTN (public services telephone network): ISDN or analog connection. If
your model features both analog and ISDN interfaces, please observe that
you can only activate one of these two options.
You then select the type of telephones that are to be used: SIP, ISDN or
analog users (analog users are not available on all models).
Set the country in which the LANCOM Business-VoIP-Router is to be
operated.
The local VoIP domain can be left as 'internal', unless a different domain
is required for operation with another system (in most cases this is
unnecessary).

LANCOM VoIP Routers: PBX Functionalities
Chapter 3: Configuring the VoIP functions
18
EN
You then activate your ISDN or analog connection for voice
communications, so that you can use this connection to telephone to the
public telephone network.
With an ISDN connection, you can select which of the available ISDN
interfaces is to be used for external telephone calls.
For an analog connection, you can define the internal telephone number
(or hunt group) that incoming calls are to be forwarded to.
Depending on the model, the wizard may ask you to set the protocol
required by the ISDN interfaces for external telephony. Set the protocol for
each interface to 'Auto (TE only)'.
If you use an ISDN connection to telephone via the public telephone
network, you can give every external telephone number (MSN or DDI) a
corresponding internal telephone number. Use the allocation in your
dialing plan to help you with this. At the same time, if applicable, you
select the ISDN interface over which these external telephone numbers
receive calls. If multiple ISDN interfaces to the exchange line have been
configured as point-to-point connections, then you also have to select
each DDI that corresponds to these interfaces.
In case you wish to use an MSN or DDI as a central telephone number
for a group of subscribers (hunt group), then with the help of your
dialing plan you can enter the internal telephone number for the
group here, e.g. '10' to reach the subscribers '11', '12', '13', etc.

You can skip the configuration of SIP users, assuming that you do not
require the SIP users to register with user name and password.
If your model has free ISDN interfaces for connecting ISDN terminal
equipment, you can select which of these interfaces are to be used for
connecting internal terminal devices.
Depending on the model, the wizard may ask you to set the protocol
required by the ISDN interfaces to connect these internal terminal devices.
The protocol should be set to 'DSS1 NT' for point-to-multipoint
connections (if, for example, you wish to connect individual telephones
directly to the corresponding interface) or to 'DSS1 NT point to point' for
point-to-point connections.
