u Press a button each time you make a
call to indicate whether you want to
make a call via the fixed network or via
the Internet (page 10).
u Register up to six handsets to your base
station. With your base station you can
make two calls simultaneously via VoIP,
or one call over the fixed network and
one call via VoIP.
u Configure the phone connection for
VoIP without a PC. Your phone’s connection assistant downloads general
data about your VoIP provider from
the Internet and guides you through
entering your personal data (VoIP/SIP
account). This makes it easy for you to
start using VoIP.
u If necessary, make any further VoIP
settings on a PC. The phone has a Web
interface (Web configurator) that can
be accessed via your PC’s Web browser
(page 22).
u Assign your own password (system
PIN) to protect your device and the
Web configurator from unauthorised
access (page 20).
u Send and receive SMS messages via
the fixed network (page 16).
u Use your phone to obtain information
about new e-mail messages in your
mailbox without a PC (page 18).
u Save up to 150 numbers and names in
your handset (page 14).
u Download your Outlook contacts from
a PC into your handset. Or back up the
handset directory on your PC.
u You can programme the keys of your
phone with important phone numbers.
The phone number is then dialled by
simply pressing the respective key
(page 14).
u Keep your hands free while making
calls. Use the handsfree function on
your handset or use a convenient
headset (accessory, not included in
the scope of delivery).
u Use your handset as an alarm clock
(page 20).

user guide for your DP450 at
Your DP450 has a protected operating system
that offers increased security against
viruses from the Internet.

The licenses for most software are designed to
take away your freedom to share and change it.
By contrast, the GNU General Public Licenses
are intended to guarantee your freedom to
share and change free software--to make sure
the software is free for all its users.
This license, the Lesser General Public License,
applies to some specially designated software
packages—typically libraries—of the Free
Software Foundation and other authors who
decide to use it. You can use it too, but we
suggest you first think carefully about whether
this license or the ordinary General Public License
is the better strategy to use in any particular case,
based on the explanations below.
When we speak of free software, we are
referring to freedom of use, not price. Our
General Public Licenses are designed to make
sure that you have the freedom to distribute
copies of free software (and charge for this
service if you wish); that you receive source
code or can get it if you want it; that you can
change the software and use pieces of it in new
free programs; and that you are informed that
you can do these things.
To protect your rights, we need to make
restrictions that forbid distributors to deny you
these rights or to ask you to surrender these
rights. These restrictions translate to certain
responsibilities for you if you distribute copies
of the library or if you modify it.
For example, if you distribute copies of the
library, whether gratis or for a fee, you must
give the recipients all the rights that we gave
you. You must make sure that they, too, receive
or can get the source code. If you link other
code with the library, you must provide
complete object files to the recipients, so that
they can relink them with the library after
making changes to the library and recompiling
it. And you must show them these terms so
they know their rights.
We protect your rights with a two-step method:
(1) we copyright the library, and (2) we offer
you this license, which gives you legal
permission to copy, distribute and/or modify
the library.
To protect each distributor, we want to make it
very clear that there is no warranty for the free
library. Also, if the library is modified by
someone else and passed on, the recipients
should know that what they have is not the
original version, so that the original author’s
reputation will not be affected by problems
that might be introduced by others.
Finally, software patents pose a constant threat
to the existence of any free program. We wish
to make sure that a company cannot effectively
restrict the users of a free program by obtaining
a restrictive license from a patent holder.
Therefore, we insist that any patent license
obtained for a version of the library must be
consistent with the full freedom of use
specified in this license.
Most GNU software, including some libraries, is
covered by the ordinary GNU General Public
License. This license, the GNU Lesser General
Public License, applies to certain designated
libraries, and is quite different from the
ordinary General Public License. We use this
license for certain libraries in order to permit
linking those libraries into non-free programs.
When a program is linked with a library,
whether statically or using a shared library, the
combination of the two is legally speaking a
combined work, a derivative of the original
library. The ordinary General Public License
therefore permits such linking only if the entire
combination fits its criteria of freedom. The
Lesser General Public License permits more lax
criteria for linking other code with the library.
We call this license the “Lesser” General Public
License because it does Less to protect the
user’s freedom than the ordinary General
Public License. It also provides other free
software developers Less of an advantage over
competing non-free programs. These
disadvantages are the reason we use the
ordinary General Public License for many
libraries. However, the Lesser license provides
advantages in certain special circumstances.
For example, on rare occasions, there may be a
special need to encourage the widest possible
use of a certain library, so that it becomes a defacto standard. To achieve this, non-free
programs must be allowed to use the library. A
more frequent case is that a free library does
the same job as widely used non-free libraries.
In this case, there is little to gain by limiting the
free library to free software only, so we use the
Lesser General Public License.
In other cases, permission to use a particular
library in non-free programs enables a greater
number of people to use a large body of free
software. For example, permission to use the
GNU C Library in non-free programs enables
many more people to use the whole GNU
operating system, as well as its variant, the
GNU/Linux operating system.
Although the Lesser General Public License is
Less protective of the users’ freedom, it does
ensure that the user of a program that is linked
with the Library has the freedom and the
wherewithal to run that program using a
modified version of the Library.
The precise terms and conditions for copying,
distribution and modification follow. Pay close
attention to the difference between a “work
based on the library” and a “work that uses the
library". The former contains code derived from
the library, whereas the latter must be
combined with the library in order to run.
0. This License Agreement applies to any
software library or other program which
contains a notice placed by the copyright
holder or other authorized party saying it may
be distributed under the terms of this Lesser
General Public License (also called “this
License"). Each licensee is addressed as “you".
A “library” means a collection of software
functions and/or data prepared so as to be
conveniently linked with application programs
(which use some of those functions and data)
to form executables.
The “Library", below, refers to any such
software library or work which has been distributed under these terms. A “work based on the
Library” means either the Library or any
derivative work under copyright law: that is to
say, a work containing the Library or a portion
of it, either verbatim or with modifications and/
or translated straightforwardly into another
language. (Hereinafter, translation is included
without limitation in the term “modification".)
"Source code” for a work means the preferred
form of the work for making modifications to it.
For a library, complete source code means all
the source code for all modules it contains, plus
any associated interface definition files, plus
the scripts used to control compilation and
installation of the library.
Activities other than copying, distribution and
modification are not covered by this License;
they are outside its scope. The act of running a
program using the Library is not restricted, and
output from such a program is covered only if
its contents constitute a work based on the
Library (independent of the use of the Library
in a tool for writing it). Whether that is true
depends on what the Library does and what
the program that uses the Library does.
1. You may copy and distribute verbatim copies
of the Library’s complete source code as you
receive it, in any medium, provided that you
conspicuously and appropriately publish on
each copy an appropriate copyright notice and
disclaimer of warranty; keep intact all the
notices that refer to this License and to the
absence of any warranty; and distribute a copy
of this License along with the Library.
You may charge a fee for the physical act of
transferring a copy, and you may at your option
offer warranty protection in exchange for a fee.
2. You may modify your copy or copies of the
Library or any portion of it, thus forming a work
based on the Library, and copy and distribute
such modifications or work under the terms of
Section 1 above, provided that you also meet
all of these conditions:
a) The modified work must itself be a software
b) You must cause the files modified to carry
prominent notices stating that you changed
the files and the date of any change.
c) You must cause the whole of the work to be
licensed at no charge to all third parties under
the terms of this License.
d) If a facility in the modified Library refers to a
function or a table of data to be supplied by an
application program that uses the facility, other
than as an argument passed when the facility is
invoked, then you must make a good faith
effort to ensure that, in the event an application does not supply such function or table, the
facility still operates, and performs whatever
part of its purpose remains meaningful.
(For example, a function in a library to compute
square roots has a purpose that is entirely welldefined independent of the application.
Therefore, Subsection 2d requires that any
application-supplied function or table used by
this function must be optional: if the application does not supply it, the square root function
must still compute square roots.)
These requirements apply to the modified work
as a whole. If identifiable sections of that work
are not derived from the Library, and can be
reasonably considered independent and
separate works in themselves, then this
License, and its terms, do not apply to those
sections when you distribute them as separate
works. But when you distribute the same
sections as part of a whole which is a work
based on the Library, the distribution of the
whole must be on the terms of this License,
whose permissions for other licensees extend
to the entire whole, and thus to each and every
part regardless of who wrote it.
Thus, it is not the intent of this section to claim
rights or contest your rights to work written
entirely by you; rather, the intent is to exercise
the right to control the distribution of
derivative or collective works based on the
In addition, mere aggregation of another work
not based on the Library with the Library (or
with a work based on the Library) on a volume
of a storage or distribution medium does not
bring the other work under the scope of this
3. You may opt to apply the terms of the
ordinary GNU General Public License instead of
this License to a given copy of the Library. To do
this, you must alter all the notices that refer to
this License, so that they refer to the ordinary
GNU General Public License, version 2, instead
of to this License. (If a newer version than
version 2 of the ordinary GNU General Public
License has appeared, then you can specify that
version instead if you wish.) Do not make any
other change in these notices.
Once this change is made in a given copy, it is
irreversible for that copy, so the ordinary GNU
General Public License applies to all subsequent
copies and derivative works made from that
This option is useful when you wish to copy
part of the code of the Library into a program
that is not a library.
4. You may copy and distribute the Library (or a
portion or derivative of it, under Section 2) in
object code or executable form under the terms
of Sections 1 and 2 above provided that you
accompany it with the complete corresponding
machine-readable source code, which must be
distributed under the terms of Sections 1 and 2
above on a medium customarily used for
software interchange.
If distribution of object code is made by
offering access to copy from a designated
place, then offering equivalent access to copy
the source code from the same place satisfies
the requirement to distribute the source code,
even though third parties are not compelled to
copy the source along with the object code.
5. A program that contains no derivative of any
portion of the Library, but is designed to work
with the Library by being compiled or linked
with it, is called a “work that uses the Library".
Such a work, in isolation, is not a derivative
work of the Library, and therefore falls outside
the scope of this License.
However, linking a “work that uses the Library”
with the Library creates an executable that is a
derivative of the Library (because it contains
portions of the Library), rather than a “work
that uses the library". The executable is
therefore covered by this License.
Section 6 states terms for distribution of such
When a “work that uses the Library” uses
material from a header file that is part of the
Library, the object code for the work may be a
derivative work of the Library even though the
source code is not.
Whether this is true is especially significant if
the work can be linked without the Library, or if
the work is itself a library. The threshold for this
to be true is not precisely defined by law.
If such an object file uses only numerical
parameters, data structure layouts and
accessories, and small macros and small inline
functions (ten lines or less in length), then the
use of the object file is unrestricted, regardless
of whether it is legally a derivative work.
(Executables containing this object code plus
portions of the Library will still fall under
Section 6.)
Otherwise, if the work is a derivative of the
Library, you may distribute the object code for
the work under the terms of Section 6.
Any executables containing that work also fall
under Section 6, whether or not they are linked
directly with the Library itself.
6. As an exception to the Sections above, you
may also combine or link a “work that uses the
Library” with the Library to produce a work
containing portions of the Library, and
distribute that work under terms of your
choice, provided that the terms permit
modification of the work for the customer’s
own use and reverse engineering for debugging such modifications.
You must give prominent notice with each copy
of the work that the Library is used in it and
that the Library and its use are covered by this
License. You must supply a copy of this License.
If the work during execution displays copyright
notices, you must include the copyright notice
for the Library among them, as well as a
reference directing the user to the copy of this
License. Also, you must do one of these things:
a) Accompany the work with the complete
corresponding machine-readable source code
for the Library including whatever changes
were used in the work (which must be
distributed under Sections 1 and 2 above); and,
if the work is an executable linked with the
Library, with the complete machine-readable
“work that uses the Library", as object code
and/or source code, so that the user can modify
the Library and then relink to produce a
modified executable containing the modified
Library. (It is understood that the user who
changes the contents of definitions files in the
Library will not necessarily be able to recompile
the application to use the modified definitions.)
b) Use a suitable shared library mechanism for
linking with the Library. A suitable mechanism
is one that (1) uses at run time a copy of the
library already present on the user’s computer
system, rather than copying library functions
into the executable, and (2) will operate
properly with a modified version of the library,
if the user installs one, as long as the modified
version is interface-compatible with the version
that the work was made with.
c) Accompany the work with a written offer,
valid for at least three years, to give the same
user the materials specified in Subsection 6a,
above, for a charge no more than the cost of
performing this distribution.
d) If distribution of the work is made by
offering access to copy from a designated
place, offer equivalent access to copy the above
specified materials from the same place.
e) Verify that the user has already received a
copy of these materials or that you have already
sent this user a copy.
For an executable, the required form of the
“work that uses the Library” must include any
data and utility programs needed for reproducing the executable from it. However, as a
special exception, the materials to be distributed need not include anything that is normally
distributed (in either source or binary form)
with the major components (compiler, kernel,
and so on) of the operating system on which
the executable runs, unless that component
itself accompanies the executable.
It may happen that this requirement contradicts the license restrictions of other proprietary libraries that do not normally accompany
the operating system. Such a contradiction
means you cannot use both them and the
Library together in an executable that you
7. You may place library facilities that are a
work based on the Library side-by-side in a
single library together with other library
facilities not covered by this License, and
distribute such a combined library, provided
that the separate distribution of the work based
on the Library and of the other library facilities
is otherwise permitted, and provided that you
do these two things:
a) Accompany the combined library with a copy
of the same work based on the Library,
uncombined with any other library facilities.
This must be distributed under the terms of the
Sections above.
b) Give prominent notice with the combined
library of the fact that part of it is a work based
on the Library, and explaining where to find the
accompanying uncombined form of the same
8. You may not copy, modify, sublicense, link
with, or distribute the Library except as
expressly provided under this License. Any
attempt otherwise to copy, modify, sublicense,
link with, or distribute the Library is void, and
will automatically terminate your rights under
this License. However, parties who have
received copies, or rights, from you under this
License will not have their licenses terminated
so long as such parties remain in full compliance.
9. You are not required to accept this License,
since you have not signed it. However, nothing
else grants you permission to modify or
distribute the Library or its derivative works.
These actions are prohibited by law if you do
not accept this License. Therefore, by modifying or distributing the Library (or any work
based on the Library), you indicate your
acceptance of this License to do so, and all its
terms and conditions for copying, distributing
or modifying the Library or works based on it.
10. Each time you redistribute the Library (or
any work based on the Library), the recipient
automatically receives a license from the
original licensor to copy, distribute, link with or
modify the Library subject to these terms and
conditions. You may not impose any further
restrictions on the recipients’ exercise of the
rights granted herein.
You are not responsible for enforcing compliance by third parties with this License.
11. If, as a consequence of a court judgment or
allegation of patent infringement or for any
other reason (not limited to patent issues),
conditions are imposed on you (whether by
court order, agreement or otherwise) that
contradict the conditions of this License, they
do not excuse you from the conditions of this
License. If you cannot distribute so as to satisfy
simultaneously your obligations under this
License and any other pertinent obligations,
then as a consequence you may not distribute
the Library at all. For example, if a patent
license would not permit royalty-free redistribution of the Library by all those who receive
copies directly or indirectly through you, then
the only way you could satisfy both it and this
License would be to refrain entirely from
distribution of the Library.
If any portion of this section is held invalid or
unenforceable under any particular circumstance, the balance of the section is intended
to apply, and the section as a whole is intended
to apply in other circumstances.
It is not the purpose of this section to induce
you to infringe any patents or other property
right claims or to contest validity of any such
claims; this section has the sole purpose of
protecting the integrity of the free software
distribution system which is implemented by
public license practices. Many people have
made generous contributions to the wide
range of software distributed through that
system in reliance on consistent application of
that system; it is up to the author/donor to
decide if he or she is willing to distribute
software through any other system and a
licensee cannot impose that choice.
This section is intended to make thoroughly
clear what is believed to be a consequence of
the rest of this License.
12. If the distribution and/or use of the Library
is restricted in certain countries either by
patents or by copyrighted interfaces, the
original copyright holder who places the
Library under this License may add an explicit
geographical distribution limitation excluding
those countries, so that distribution is
permitted only in or among countries not thus
excluded. In such case, this License incorporates the limitation as if written in the body of
this License.
13. The Free Software Foundation may publish
revised and/or new versions of the Lesser
General Public License from time to time. Such
new versions will be similar in spirit to the
present version, but may differ in detail to
address new problems or concerns.
Each version is given a distinguishing version
number. If the Library specifies a version
number of this License which applies to it and
“any later version", you have the option of
following the terms and conditions either of
that version or of any later version published by
the Free Software Foundation. If the Library
does not specify a license version number, you
may choose any version ever published by the
Free Software Foundation.
14. If you wish to incorporate parts of the
Library into other free programs whose
distribution conditions are incompatible with
these, write to the author to ask for permission.
For software which is copyrighted by the Free
Software Foundation, write to the Free
Software Foundation; we sometimes make
exceptions for this. Our decision will be guided
by the two goals of preserving the free status of
all derivatives of our free software and of
promoting the sharing and reuse of software
How to Apply These Terms to Your New
If you develop a new library, and you want it to
be of the greatest possible use to the public, we
recommend making it free software that
everyone can redistribute and change. You can
do so by permitting redistribution under these
terms (or, alternatively, under the terms of the
ordinary General Public License).
To apply these terms, attach the following
notices to the library. It is safest to attach them
to the start of each source file to most
effectively convey the exclusion of warranty;
and each file should have at least the “copyright” line and a pointer to where the full notice
is found.
<one line to give the library’s name and a brief
idea of what it does.>
Copyright (C) <year> <name of author>
This library is free software; you can redistribute it and/or modify it under the terms of the
GNU Lesser General Public License as
published by the Free Software Foundation;
either version 2.1 of the License, or (at your
option) any later version.
This library is distributed in the hope that it
will be useful, but WITHOUT ANY WARRANTY;
without even the implied warranty of
General Public License for more details.
You should have received a copy of the GNU
Lesser General Public License along with this
library; if not, write to the Free Software
Foundation, Inc., 59 Temple Place, Suite 330,
Boston, MA 02111-1307 USA
Also add information on how to contact you by
electronic and paper mail.
You should also get your employer (if you work
as a programmer) or your school, if any, to sign
a “copyright disclaimer” for the library, if
necessary. Here is a sample; alter the names:
