electric shock. In addition, any damage to the casing or to the device itself
can be life-threatening.
•Only connect the device connection cable with sockets that are designed
for that purpose.
•Replace damaged connection lines immediately.
•Always have a professional carry out repairs immediately. Please contact
your dealer or the manufacturer directly.
•Use only original accessories.
•Do not touch the contact points with pointed, metallic or moist objects.
•Do not carry the device by the connection cables.
•Use the cable channels at the bottom of the telephone to carry the load.
Warning: Any liquid that penetrates the casing can result in a life-threa-
tening electric shock or can damage or destroy or the device.

Proper Use
Important: Auerswald products are not designed, manufactured, or intended
for use or resale in environments requiring fail-safe performance, such as in
the operation of life-support systems and/or nuclear facilities. Use or sale of
our products for these purposes is only allowed with prior written permission
by Auerswald for each individual incident.
Important:
Improper use may cause, for example, functional restrictions or inter-
ference, the destruction of the device or, in a worst case scenario, personal
injury.
If you are still not sure of the intended use of the product after reading the
following section, please contact your vendor.
The COMfortel VoIP 2500 AB is a VoIP system telephone. The device is designed to be
integrated in a local network (LAN) as a VoIP end device on one of the following Auerswald
PBXs:
•COMmander Basic.2 (19")
•COMmander Business (19")
•COMpact 3000
•COMpact 5010 VoIP
•COMpact 5020 VoIP
Important:
To support internal IP telephony, the PBXs COMpact 5010 VoIP, COMpact
5020 VoIP, COMmander Basic.2 or COMmander Business need firmware
version 3.0 or higher. The PBX COMpact 3000 needs firmware version 3.6A
or higher. When using a COMpact 3000 analog or COMpact 3000 ISDN,
VoIP channels must be obtained at the Upgrade Center and enabled by it.
This device is not designed to be connected to a PBX from another manuf-
acturer.
The system telephone is not cordless and is intended for use in closed, dry rooms.
The system telephone is different from “normal telephones” connected to PBXs in that it is
especially easy to use, among other things. Most of the functions available on the PBXs such
as internal and external calls, call protection and call forwarding can be operated over the

display or by simply pressing previously programmed buttons. In addition, the PBX system
telephone supports offered functions for telephone switch boards (for example, the Waiting
Field) and various telephone number lists (for example, the telephone book or call list).
The system telephone can be configured either using the menu on the telephone display or via
the configuration manager that is accessible via the web server integrated in the telephone. The
required PC is connected either directly to an Ethernet port on the telephone (see ) or must be
in the same network.
The system telephone allows you to make calls by using both the connected receiver and the
integrated loud speakers (hands-free calling). Another option is to connect a headset (not
included in the package).
The system telephone supports the operation of cable-connected headsets as well as wireless
headsets (headsets with a DHSG interface, for example, from GN and Plantronics).
Das Systemtelefon kann mit bis zu drei Tastenerweiterungsmodulen COMfortel Xtension30
(nicht im Lieferumfang) um frei programmierbare Funktionstasten erweitert werden. Die
Module werden wahlweise links oder rechts am Telefon angebracht. Im Vollausbau stehen
dann 105 frei programmierbare Funktionstasten zur Verfügung.
Up to three COMfortel Xtension30 key extension modules (not included in the delivery) can be
attached to the system telephone in order to add freely programmable function keys. The
modules can be attached on either the left or the right side of the telephone. A completely
extended system provides 105 freely programmable function keys.

Accessories and service parts can be bought at specialised stores or in the
