Functionality
Provided it is not already present on
your PC the installation of
OpenPhone IPC automatically installs a current version of DirectX.
With the standard installation of DirectX, DirectSound is configured
with default settings that avoid
processor-load. Possibly the audio
quality will suffer because of this.
With the following steps the quality
can be adapted.
Note: To adapt the DirectSound audio quality, you will require administrator privileges!
1. Select from Control Panel:
Sounds and Multimedia the tab
Audio.

OpenPhone IPC Configuration
When starting the OpenPhone IPC
for the first time, automatically the
configuration assistant is opened
with which the OpenPhone IPC can
be configured. These options can
subsequently be accessed via the
Options menu entry.
OpenCom Tab
The here required data
(OpenCom 100’s IP address and the
device ID) can be obtained from your
system administrator. The Connec-
tion setting should only be changed
if you want to connect to the
OpenCom 100 via a RAS dial-up connection.
Display Tab
This tab is not available for the interface-less version of the
OpenPhone IPC. Select the desired
interface from the Skin selection
and the Device type.
Activate the Truecolor version for
optimal display quality. This option
is only available if the graphic card
OpenPhone IPC OpenPhone IPC Configuration

permits a colour depth of 16 bit
(65536 colours) or more.
Audio Tab
Select the sound card for the audio
input and output. The selection is
necessary if multiple sound cards or
sound-card drivers are installed. The
settings for input and output must
refer to the same device. Even when
using DirectSound, the system’s
sound and multimedia settings must
select the same device for input and
output.
uration you should deactivate the
Echo suppression option.
The Local echo option is only available if your sound card supports the
direct output of microphone data to
the loudspeaker. Thereby the speech
in suppressed form is playback on
your loudspeaker, without delay, as
you are accustomed from your telephone. This option is only recommendable when using a headset.
The Use DirectSound option allows
multiple applications to output
acoustic signals simultaneously. In
this way, you can also use, for example, the OpenPhone IPC parallel to
playing music data. If you experience problems with the input and
output of audio data, then deactivate this option.
The Echo suppression option servers to reduce the audible echo for
the call-partner. A echo will be audible if you use a loudspeaker and microphone or a badly suppressed
headset. If this option is activated
then as soon as the call-partner
speaks during calls via the receiver,
the microphone is suppressed and
for hands-free calls it is muted. With
DirectSound under Microsoft
Windows XP, AEC (Acoustic Echo
Cancellation) is used. For this config-

Usage
The OpenPhone IPC can be used selectively with the mouse or the keyboard of the workplace computer.
The usage corresponds to an
OpenPhone 61, OpenPhone 63 or
OpenPhone 65.
Page 15
When inputting via the keyboard,
pay attention to the input mode of
the terminal. Between numeric and
alphanumeric input is differentiated.
For example, if you enter a call
number you will be in numeric input
mode. When you search for a name
in the telephone book, you will be in
alphanumeric input mode. On the
terminal to enter a “C”, for example,
you must press the “2” key three
times. When inputting letter “C” on
the keyboard, the OpenPhone IPC
automatically converts it to the corresponding digit key. For the entry of
digits in numeric input mode you
should always use the numeric pad
of your workplace computer.
Press the shift key on the workplace
computer and simultaneously a second key in order to enter a long keypress on the OpenPhone IPC. For example, the OpenPhone IPC’s ABC key
has the functions telephone book
(“short”) and language selection
(“long”). Example: with the key combination Ctrl+A you open the telephone book. With the key combination Shift+Ctrl+A you reach the
language selection.

Volume Settings
During the call state, when playing
back a recording or doing any other
actions that use the sound card, the
OpenPhone IPC temporarily modifies the volume settings of the workplace computer. This volume setting
is preset in the Options dialogue. On
completion of the action, the previous volume setting is restored.
Note: If during a call the volume or
microphone sensitive of the sound
card are changed, then this configuration is saved for the OpenPhone IPC
and used for future calls.
Audio Functionality
In addition to the telephony functionality, the OpenPhone IPC permits the recording of calls and the
recording of audio e-mails. Furthermore the OpenPhone IPC can be
used as an answering machine.
The operation of these functions is
done via the three extra keys “Rec”,
“Stop” and “Play”.
The keys “Rec” and “Play” can, depending on the operational state,
change to pause keys.
The function of the keys is dependent on whether the answering machine has been activated or not. The
playback of answering machine
messages and recordings is also possible via Drag & Drop with an audio
file.
