Preface
Thank you for your confidence in us!
LANCOM VoIP Routers provide the comprehensive functions of an access
router, professional firewall and high-quality VPN gateway and WLAN access
point in a single, compact device. They thus combine investment protection
and cost savings as a reliable voice over IP solution for small and mid-sized
enterprises, home and branch offices.
LANCOM 1823
VoIP only LANCOM Wireless Routers and LANCOM Access Points can be oper-
ated either as self-sufficient Access Points with their own configura-
tion (WLAN modules in "Access Point mode“) or as components in a
WLAN infrastructure, which is controlled from a central
WLAN-Controller ("managed mode"). Please observe the correspond-
ing notices to this in this documentation.
Standard features of the different models are integrated interfaces for ADSL
and ISDN, and a LAN switch. LANCOM 1723 VoIP additionally provides inter-
faces for analog telephone systems. Along with the analog interfaces,
LANCOM 1823 VoIP also provides professional WLAN technology.
In addition to data communications functions, VoIP support transforms
LANCOM Routers into fully fledged, integrated VoIP communications solu-
tions. Along with Quality of Service functions which are optimized for VoIP, the
LANCOM VoIP Routers offer the full range of options required for voice com-
munications over data networks and the step-by-step, cost-effective and sim-
ple migration from existing telecommunications systems to corporate Voice
over IP. The particular characteristics of LANCOM VoIP Routers include, among
others:
PBX functions for analog, ISDN and SIP subscribers
Site connectivity of data and voice via VPN
SIP proxy and registrar for registration with providers and upstream VoIP
PBXs
SIP trunking for multiple parallel lines with extension numbers over a sin-
gle account with a switchboard number.
SIP gateway with transparent transition between SIP and ISDN/analog
telephony
SIP remote gateway provides local SIP, ISDN or analog lines to remote
IP-PBXs.

Chapter 1: Introduction

EN
The Internet is available virtually everywhere and typically has low access
costs. Significant savings can thus be achieved in relation to switched or ded-
icated connections, especially over long distances.
The physical connection no longer exists directly between two participants;
instead, the participants rely on their connection to the Internet. The access
technology used is not relevant in this case: Broadband technology such as
DSL (Digital Subscriber Line) is ideal. A conventional ISDN line can be used
too.
The technologies of the individual participants do not have to be compatible
to one another, as would be the case for conventional direct connections. A
single Internet access can be used to establish multiple simultaneous logical
connections to a variety of remote sites.
The resulting savings and high flexibility makes the Internet (or any other IP
network) an outstanding backbone for a corporate network.
1.3 Firewall
The integrated stateful-inspection firewall is an effective barrier to unwanted
data traffic as it only permits the entry of data as a response to outgoing data
traffic. The IP masquerading function in the router conceals LAN workstations
accessing the Internet behind a single public IP address. The true identities (IP
addresses) of the individual workstations remain masked. Router firewall fil-
ters allow the blocking of individual IP addresses, protocols and ports. MAC
address filters also offer effective control over the access of LAN workstations
to the IP routing functions in the device.
Further important features in the firewall are:
Intrusion detection
FIREWALL Router
PC
Server
PC
INTERNET

Chapter 1: Introduction

EN
Attempts to break in to the local network or central firewall are recog-
nized, repelled and recorded by the Intrusion Detection System (IDS) in the
LANCOM. There is a choice of alarms including in-device logging, e- mail
messaging, SNMP traps or SYSLOG alarms.
Denial-of-Service protection
In addition to conventional break-ins, attacks from the Internet may aim
to block the availability of individual services. For this reason, the
LANCOM router is equipped with appropriate security mechanisms to rec-
ognize popular hacker attacks and guarantee router functionality.
Quality of Service/traffic management
The term Quality of Service (QoS) embraces a range of functions in your
LANCOM. QoS functions consider the powerful classification methods
used by firewalls (e.g. restriction to subnets, individual workstations or
certain services). These enable Quality of Service to be very precisely con-
trolled.
By guaranteeing a minimum bandwidth, precedence can be assigned to
enterprise-critical applications, VoIP telephony or certain user groups.
Details about the functions of the LANCOM Router stateful-inspection
firewall are available in the reference manual.
1.4 Voice over IP
The term Voice over IP (VoIP) refers to voice communications over computer
networks based on the Internet protocol (IP). The core idea is to provide the
functions of traditional telephony via cost-effective and wide-spread net-
working structures such as the LAN or Internet. VoIP itself is not a standard,
rather it is a collective term for the various technologies (equipment, proto-
cols, voice encoding, etc.) which make voice communications in IP networks
possible.
1.4.1 Example Applications
Voice over IP solutions offers advantages across a broad spectrum of applica-
tions, starting with small companies and extending to large corporations with
extensive networks of subsidiaries. In the following section, we will demon-
strate a number of examples.
Detailed instructions on configuration are available in the PBX Func-
tions manual or in the LCOS reference manual.
