Forum Phone 515/
525/535
System Telephones
The Forum Phone 515, Forum Phone 525 and Forum Phone 535
are corded system telephones that you can operate on your
Forum 500 / Forum 5000 communications system. The MenuCard
display makes your telephone easy to operate and gives you fast
access to your system’s wide range of different functions and fea-
tures.
The Forum Phone 525 and the Forum Phone 535 have the same
functionality. The only difference between them is the size of the
display and the number of programmable keys available. The
Forum Phone 515 offers the most functions of these two tele-
phones with the following exceptions: the Forum Phone 515 has
just one trunk key available (please refer to page 15) and the “Hot
Desking” feature is not supported (please refer to page 92). The
Forum Phone 525 and Forum Phone 535 telephones can also be
expanded via additional key extensions which offer additional pro-
grammable keys (please refer to page 32).
The Forum Phone 525 and the Forum Phone 535 are also availa-
ble as IP telephones (Forum IPhone 525 and Forum IPhone 535).
These telephones have the same functionality as the standard
system telephones. All of the functions described in this guide are
also available for the IP telephones. The chapter VoIP Telephones
starting on page 96 contains a short summary of the information
necessary for the IP system telephone user.
You can activate the features and programme functions on the tel-
ephones themselves, or equally conveniently, use the Configura-
tor of the communications system.

About this User Guide
The description of the various functions of your system telephone
covers (unfortunately) many pages. Not every user has the time
and leisure to read the guide from start to finish before telephon-
ing for the first time. The following chapters are mandatory read-
ing before using your telephone:
zSafety Precautions starting on page 9: These tips are for your
own safety and help you to protect the telephone from
damage!
zInstallation Site starting on page 9
zKey Assignments starting on page 12 and Display and
MenuCards starting on page 23: Here is an overview of the
features of your telephone.
zIn a hurry?: A Brief Explanation of Important Functions
starting on page 40: Read this chapter for quick telephoning
access.
Take enough time to also read the rest of this user guide and
familiarize yourself with the features of your telephone. You will
become acquainted with many new functions which you can use
for the practical organisation of your communications. Use the
index for fast information access of individual functions.
The Glossary
Should you need further information about any system features
described in this user guide, please read the “Glossary” which
comes with your communications system.
You Need Authorisation
Most of the features mentioned in this user guide are only availa-
ble to you if you have the appropriate authorisation. This will be
set up by your system administrator when configuring the com-
munications system. If you are unable to use a particular feature
or have any questions, consult your system administrator.

Using Your Telephone
Safety Precautions
WARNING! Do not open the telephone or the connected
accessories, as this could lead to you touching live parts.
Note: Repairs must only be carried out by authorised Belgacom
service personnel.
zKeep fluids and chemicals away from the telephone and its
accessories.
zUse only the AC adapter plug included in the delivery (product
code 90035810) where necessary.
zDo not use AC adapter plugs that show visible damage (e. g.
cracks in the housing).
zConnected headsets must conform with the standard DIN EN
60 950-1, Point 6.2 (“Safety of information technology
equipment including electrical business equipment”).
Please contact your customer consultant if you require further
information about the connectable headsets, adapters and
adapter cables.
zUse a shielded CAT-5 Ethernet cable (STP cable, Shielded
Twisted Pair cable) to connect an IP telephone to a Local Area
Network (LAN).
zMake sure that no one can trip over the telephone cables.
Installation Site
Do not install the telephone or its accessories
znear water, moisture or in damp locations;
znear sources of heat or in direct sunlight;
zin unventilated rooms;
znear devices that generate strong magnetic fields, electrical
devices, fluorescent lamps, computers, radios or television
sets;

zin dusty places or places subjected to vibrations, shocks or
extreme temperature fluctuations.
Place the telephones on a non-slip surface. The surface finish of
your furniture may affect the telephone’s pedestals, softening
them and causing them to leave undesirable marks on your furni-
ture.
Cleaning
Simply wipe your telephone with an antistatic or slightly damp
cloth. Never use a dry cloth or a cleaning agent.
Attaching the Pedestals and Adjusting the
Inclination
To pull the pedestals out, press them in slightly (a). To replace
them, press the pedestals in slightly (a) and push them back in
(b). The pedestals lock into place in the notches.

There are four positions of inclination possible on the
Forum Phone 525 and on the Forum Phone 535 (see A, B, C and
D), depending upon the direction in which the pedestals have
been attached.
Wall Mounting
To mount your telephone to the wall, remove the pedestals. Using
a screwdriver, pry the retention pin (1) for the handset out of its
receptacle, turn it upside down (2) and insert it again.
To mount your telephone to the wall, drill two holes at 119 mm
distance apart. Insert 6 mm screws in the holes. Make sure their
heads protrude 2.5 to 3 mm from the wall and mount the tele-
phone onto the screws.

Trunk Key (Call Key 1)
gThe trunk key of the telephone (also: call key 1) is occu-
pied by your internal call number (main number). The key is
located to the left of the display, and is labelled with your internal
call number (or optionally, with a text programmed by the system
administrator). Refer to the respective illustration in the chapter
Key Assignments starting on page 12 to determine the position of
the key on your equipment. Your internal call number is assigned
to an external call number where you can be reached when being
called from an external number. It is possible to assign several
external call numbers to the key. If you wish to make a call, lifting
the handset seizes the key (and the trunk line); you can immedi-
ately dial an internal or external number (depending on the sys-
tem setting). Long pressing the key displays a MenuCard which
allows you to programme the key’s settings (see the section enti-
tled MenuCard “Prog. call key” starting on page 139).
A system setting makes it possible to have your internal number
assigned to other telephones as well. Calls will then be signalled
to other telephones simultaneously.
The LED of the key indicates the current status, see also the chap-
ter Signalling on the Call Keys starting on page 50.
For the System Administrator: Setting the Trunk Keys of
the System Telephones
zThe internal call number for a system telephone is configured
in the Configurator, Telephony: Ports: Upn menu or for IP
phones respectively in the Configurator, Telephony:
Devices: VoIP Phones menu. The assigned internal call
number is automatically allocated to the trunk key (call key 1).
zThe assignment to external call numbers takes place in the
Configurator, Telephony: Call Distribution menu.
Programmable Keys
gThe additional keys to the left of the display are free pro-
grammable keys. The system administrator can assign other
internal call numbers to these keys for you as additional trunk
keys (call keys). These keys have also been assigned to external
call numbers at which you can be reached from an external

Key Assignments16
Forum Phone [phone] System Telephones
number. In order to make a call with a trunk key, first press the
key and then dial the call number.
Note: Only call key 1 can be configured as a trunk key on the
Forum Phone 515 system phone (please refer to page 15).
The system administrator can also assign the programmable keys
as call keys for team functions. Information on the use of team
functions can be found in the chapter Team Functions starting on
page 99.
