Introduction – Important Information
Differences using various Telephones

System telephones, ISDN telephones and Standard VoIP telephones
as well as analog telephones with dual-tone multi-frequency signal-
ling (DTMF) or with pulse dialling method (PD; only with functional
restrictions) can be used with the PBX.
Important: To enable internal IP telephony on standard VoIP tele-
phones and the system telephone COMfortel VoIP 2500 AB, the PBX
needs firmware version 3.0.
There are some differences when using or programming them. Famil-
iarize yourself – especially with ISDN telephones and Standard VoIP
telephones – with the use of your telephone (see manual of the tele-
phone).
Analog Telephones (Pulse Dial and DTMF)
If you are already in a conversation condition with another subscriber
(internal or external), you will have to press the FLASH key (signal
key, R-Key) in case of a DTMF telephone before you are dialling a
digit e.g. for Call Forwarding. In this manual the FLASH key is repre-
sented by the symbol
F
.
The flash key does not exist on an PD telephone. Besides this the
keys
*
and
#
do not exist either or no function has been assigned to
these keys. As these keys are necessary for most type of calls as well
as for the settings (programming), these function cannot be oper-
ated with PD telephones! They can only start calls and accept them.
If your telephone offers both dialling methods, you have to re-pro-
gram it to DTMF.
Analog T-Net-Telephones
With some of the analog DTMF telephones some of the T-Net func-
tions (e.g. Call Forwarding) are assigned to special menus or function
keys. If you use such a telephone as an internal subscriber tele-
phone, you will be able to use this comfortable operation also for
some functions of the PBX. These functions are marked with the T-
Net-arrow
T
. If you find this advice and you like to use the T-
Net functions of your telephone, please read the manual of your tele-
phone. Please pay attention to the preceding “0“ (exchange line
access digit) if you enter the telephone number. Instead of the
“announcement of the public exchange“ you will hear the acknowl-
edgement tone for a successful programming.
ISDN Telephones
In order to be able to operate your ISDN telephone, you will have to
get familiar with its functionality. Therefore it is necessary to read the
manual of the telephone and to read the ISDN telephone help files of
Auerswald provided that your telephone is listed there (available on
the Auerswald CD and the Auerswald homepage). It is absolutely
necessary to know with which key or with which menu a Query can
be started (e.g. hold key or R-key). This function is required if you see
the following function symbol
F
in the manual. In some of the func-
tions you will have to rely on the menus/function keys of the tele-
phone. “Conference“, “Alternation“, “Accept/refuse waiting Call“, “Fin-
ish Query“ and “finish a Query on busy target“ belong to these
functions. Please pay attention to the ISDN advice arrow
I
.
The digits to be dialled for analog telephones have to be ignored in
this case.
System Telephones
The major portion of PBX functions can be handled with all connected
telephones as described in this manual. With the system telephones
COMfortel 1100/1500/2500/2500 AB/VoIP 2500 AB as well as COM-
fort 1000/1200/2000 plus the use is much more comfortable because
the most important functions can be controlled via menu/function key
(see advice). This operation is described in the manual of the tele-
phone. Some of the described PBX functions can only be used with
the system telephones as stated in the description.
Standard VoIP Telephones
On most standard VoIP telephones, functions such as “Call waiting,”
“Conference,” “Query calling” and “Hold” are not carried out via the
PBX but rather on the phone itself. Therefore, the instructions for
operating these functions may deviate from the descriptions in this
manual. Please refer to the manual for the telephone in question.
Normally, pressing the pound key # on a standard VoIP telephone ini-
tiates a dialling procedure. Since this key is required for numerous
functions as well as for all settings (programming), using the pound
key for these actions is not possible on most standard VoIP tele-
phones! Please refer to the manual for the telephone in question.
