If you have a Konftel 200W with a serial number that ends with R2B (or higher) you can activate DTMF by pressing MENU then R+9. The display will show DTMF and then reboot. To disable DTMF press MENU then R+4.

Do as follows:

• Call the first participant. Wait for an answer.
• Then press R (F in America) and wait for a new dialling tone.
• Call the second participant. Wait for an answer.
• Press R (F in America) then 3 (this command can be different in different PBX environment). Three participants are now connected in a conference call. To connect more than 3 participants (provided that the PBX supports it) continue as follows:
• Press R (F in America) again. Wait for a new dialling tone.
• Call the next participant. Wait for an answer.
• Finish with R (F in America) followed by 3. Repeat this for as many participants as the PBX supports. Note that 3-party calls do not work with certain PBX's.

If three parties wish to have a conference call, it can be done with the help of the three party conference call function in the telephone network/PBX. If more than three parties are to engage in the conference call, you can use a conference call service provided by a service provider.

The vendor list will not affect the registration part. It is only used to adjust the levels to the different systems. Please select "Other" if your system is not in the list.

Please try to register without a PARK code. Just press OK when the device asks for a PARK code. Then the Konftel will try to find the correct PARK code.

Perform a manual room calibration (trimming). This is heard as static of about 0.5 seconds in length. From the remote or the keyboard, do the following: * Konftel 50 and 60W: Press the Trim button. * Konftel 100/D and 100/R: Press the + and - volume buttons simultaneously. * Konftel 100, 200 and 200NI: Press the volume buttons (down arrow /up arrow) simultaneously or press the trim button on the remote. You could also try to lowering the volume on the Konftel to improve the audio quality.

You have to change the default R pulse/Flash time. It can vary from country to country but also depend on the PBX to which Konftel is connected.

Konftel has a built-in encryption based on derived or static 64 bits cipher keys.

1. Your PBX does not support mulipart calls. Contact your PBX reseller for upgrading.

DECT has a built-in 128-bit authentication and identification. The Konftel has to be registered with an AC code (PIN) in the DECT system before starting using it.

WLAN (802.11) operates on the 2,4GHz band. DECT operates on the 1880-1900 MHz frequency band (Europe). Therefore there should not be any interference between DECT and WLAN.

Decrease the volume a notch on the Konftel as shown in the instructions in the user guide.

There is nothing wrong. Some Konftel telephones make this noise at the beginning of every call. Either once or three times. When this click occurs, a room calibration takes place to ensure that the telephone works perfectly in your room. When the click occurs three times, it is because the room has difficult acoustics, such as a long echo (longer than 0.5 seconds) or the level of background noise is louder than 45 dBA. Because of the environment, the telephone does not then provide optimal performance.

Yes, Konftel has a optional DECT base station that can be wallmounted. The Konftel DECT basestation is connected directly to a analog telephone line/extension. With one base the DECT coverage is limited to up to 50 meters between the base and the Konftel. It can be registered to 4 different base systems or Konftel DECT base stations. In this way the coverage can be complete.
