Set up

• How do I set up a conference call with a Konftel telephone?
  • 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.
• I have connected my Konftel 200NI to our switchboard with an ISDN connection, but I get no connection. What is the problem?
  • The Konftel 200NI requires ISDN/So (ISDN S zero) in the telephone jack. Also check that the telephone is set to ISDN or Auto mode.
• I hear an echo during the call. What should I do?
  • 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.
• I press the R/F button but don't get a new dial tone when I want to call next participant. What's wrong?
  • 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.

Other

• My Konftel is connected to a PBX. I follow the instructions for multiparty calls, but it doesn't work.

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

    2. Your PBX needs another command than R3 to connect more parties, read the table below. Note that the commands can differ due to settings in the PBX.

Audio

• The person on the other end who called in to the meeting says they hear an echo. What should I do?
  • Decrease the volume a notch on the Konftel as shown in the instructions in the user guide.
• When connecting the telephone clicks one or more times. What is the problem?
  • 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.
