General

What documents are available for the OpenScape Desk Phones and where do I find them?

All OpenScape Desk Phones are shipped with a printed document in multiple languages providing brief instructions regarding installation and operation. All the others are here on this Wiki.

How do I get an overview of the features of the OpenScape Desk Phones?

What are the default passwords?

User Menu: no password
Admin Menu: 123456
Factory Reset: 124816

Security Advisory: ensure that the default passwords (both user and admin access) are changed to individual complex passwords when a phone gets into operation. This is especially important in deployment scenarios where remote administration via WBM (web-based management) is enabled.

How can I invoke a soft-Restart?

Press buttons osk-1.gif osk-4.gif osk-7.gif simultaneously and enter the admin password.

How can I invoke a factory reset?

Press buttons osk-2.gif osk-8.gif osk-9.gif simultaneously and enter the reset password.

Administration

Diagnostics

How can I monitor the phones IP traffic?

Best way, just configure the PC-port of your OpenScape Desk Phone as a mirror of the first one and trace phones IP/SIP traffic with a network tracer running on the PC connected to the phones PC-port.

What is a phone-trace?

It is a capture of messages and activity states of the phone.

How can I get a phone-trace?

Traces section in WBM
The tracing is enabled via the Web interface, actions are then performed on the phone, during which the trace information is captured. When the desired actions have been performed, the captured trace information can be downloaded and viewed.
The file size should be set to 2.500.000 bytes. When the file size is reached, the phone save the trace file as old trace file and begins a new one. If the new one reaches the maximum file size, the old trace file will be replaced.
You should only activate a few traces and use the function "Automatic clear before start" (old files will be deleted)

Compatibility

Can I move a Mobile User between an optiPoint and an OpenScape Desk Phone telephone and vice versa?

Cross mobility is released with the following restriction: Mobility between OpenScape Desk Phone and optiPoint410/420 phones is released but please take notice of some minor restrictions/ details to be taken into account (see information below). The "mobility log-on/ log-off" is released for mobile users logging in or off from any OpenScape Desk Phone IP to optiPoint 410/420 SIP and vice versa. However: There are a few details and shortcomings to be taken into account when it comes to creating a mobile user in DLS and the interworking of default settings especially for multi-line appearance (position of the keys while using mobility and the key layout). In order to both understand and gain an overview on details to be taken into account please refer to the "Cross Mobility" document

LDAP

Accessing the LDAP server is available on OpenScape Desk Phone IP 55G and OpenScape Desk Phone IP 35G (with SW Release V3 R3 and higher).

What is the purpose of a LDAP template?

See also: LDAP on OpenScape Desk Phone

A LDAP template has to be downloaded to the phone via local phone menu or WBM, because it contains necessary information about the search attributes and the location of all user data inside the directory.

Where do I get the template from?

It is a plain txt file and must fit your directory environment. The configuration for a Microsoft Active Directory would look like this:
OpenStage LDAP TEMPLATE (v.1)
SEARCHBASE="OU=Users,DC=microsoft,DC=com"
ATTRIB01="sn"
ATTRIB02="givenName"
ATTRIB03="telephoneNumber"
ATTRIB04="otherTelephone"
ATTRIB05="mobile"
ATTRIB06="homePhone"
ATTRIB07="company"
ATTRIB08="department"
ATTRIB09="l"
ATTRIB10="title"
ATTRIB11="mail"
EOF
If your are not using a Microsoft AD, you have to adjust the template:
OpenStage LDAP TEMPLATE (v.1)
SEARCHBASE="OU=Users,DC=yourdomain,DC=toplevel"
ATTRIB01="Last Name"
ATTRIB02="First Name"
ATTRIB03="Business phone numer 1"
ATTRIB04="Business phone numer 2"
ATTRIB05="Mobile phone number"
ATTRIB06="Home phone number"
ATTRIB07="Company"
ATTRIB08="Address 1"
ATTRIB09="Address 2"
ATTRIB10="Job function"
ATTRIB11="E-Mail address"
EOF

Configuration at the phone.

Besides the template, add the following information in the admin menu of the OpenScape Desk Phone IP: Admin --> Local functions --> Directory Settings
  • LDAP server address
  • LDAP server port
  • LDAP authentication (if Simple, add authentication information below)

Restrictions

Up to now, the address is saved in one single field, which makes it difficult to search for a complete address. It is up to the administrator to which subject of the Directory the address fields are matched with.

Web-based-Management (WBM)

With the WBM are changes in settings possible, which can also be performed in the phone-menu, but you have the adventage that you needn't be in front of the phone.
Trace-configuration is only possible in WBM.

The OpenScape Desk Phone IP 55G provide an USB master port.

What can I connect to this port?

You can connect an USB memory stick to back-up and restore personal data, like phonebook, ringer tones and pictures (for details see below). All data you find under Settings ⇒ User (no admin data).

When you plug in a USB hub it is recognised and a video camera will actually work through the USB hub, but a memory stick does not work.

What USB features can I use?

  • Backup of data into USB (with a password, and then it is encrypted)
  • Restore of data from USB (with a password, and then it is decrypted)
  • Encryption/Decryption of the backup data (storing on USB memory stick and loading data from USB memory stick is encrypted)
  • Replace backup
  • Delete backup
  • HotPlug device
  • ColdPlug device
  • Getting product name (the phone is told the USB device name)

Can I store more than one phone configuration on an USB memory stick?

Yes. It depends only on the size of memory of the USB memory stick.

Logo (Background picture)

How can I put my own company logo or background picture on the phone?

This can either be done by local phone menu or Webbased management. The logo file has to be placed on a FTP server, where the phone can download it.

What file types are supported?

OpenScape Desk Phone IP 55G supports PNG and JPG format, but PNG is the preferred file type because of the transparency feature.
A logo file has to be resized to 240 x 70 pixel
For a HowTo, see Administration Manual OpenScape Desk Phone OpenScape Voice.

How can I return to the default logo?

If you like to return to the standard logo (Siemens) feel free to download the respective file and deploy it to the phone.
Below you can find all default logo files for OpenScape Desk Phone IP 55G:
Design: Silver Blue, PNG:

240px

Design: Anthracite Orange, PNG:

240px

Screensaver

Can I use my own pictures for the screensaver slideshow?

Yes, this is possible. Easiest way doing this, is with the help of the OpenStage Manager tool. It transfers all the pictures to the phone, makes them fit best on the screen and can help saving memory.

Which formats are supported?

The supported formats are JPG and PNG.

How many pictures can be downloaded?

This depends on the memory usage for other user data (eg. phonebook entries, ringer tones). The total memory available is limited to 8 MB.

Local phonebook

Is it possible to synchronize my Outlook contacts with OpenScape Desk Phone?

This can be done with the OpenStage Manager.

Ringer tones

What file types are supported?

In general, WAV and MIDI files are supported on all 2 phone types. Additionally, OpenScape Desk Phone IP 55G can play MP3 files.

Is there a suggestion for MP3 files?

OpenScape Desk Phone IP 55G can play MP3 files from 32 kbit/s up to 320 kbit/s (stereo and mono). Because of a limitation of the space available (8 MB in total), the following is suggested:
- mono instead of stereo sound
- a constant bitrate between 64 and 96 kbit/s
- a maximum length of 15 seconds per file
See the following table for estimated file size:
64 kbit/s (mono) 80 kbit/s (mono) 96 kbit/s (mono)
Length 5 seconds 40 KB 50 KB 60 KB
Length 10 seconds 80 KB 100 KB 120 KB
Length 15 seconds 120 KB 150 KB 180 KB

How can I download my own ringer melodies to the OpenScape Desk Phone IP 55G?

This can be done by using the OpenStage Manager. As an instance of ringtones, several MP3 files can be found here.

How can I download my own ringer melodies to the OpenScape Desk Phone IP 35G?

This can be done via FTP or Deployment Service. If you want to replace it, you need to download a new file with the same name. Of course a factory resets turns the phone in the original state and eleminates individual downloaded ringer files.
MIDI files are used instead of WAV files.
