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 get the message "Analogue overcurrent" when I try to call, how can I solve that?
- This message usually appears when you have connected the Konftel to a digital line and not an analogue line that the Konftel requires.
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.

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.

Accessories

Can I use the old Konftel 200/200W/60W microphones to my Konftel?
- No, you'll need the new expansion microphones with item number 900102113.
Does the Konftel microphone switch off when extra microphones are connected to my Konftel?
- No, as opposed to the older Konftel models (200/200W/200NI), all three microphones are used.

Features

Can I record while I'm not in a call?
- Yes, you can use the Konftel 250 if you only want to record a "local" meeting. Do the following:
  
  1. Press the green off hook button (remove the analogue cable if you don't want the dial tone at the beginning)
  
  2. Start the recording by pressing the C/Rec button and confirm with "OK" on the Konftel 250.
  
  3. To stop the recording press the C/Rec button and confirm with
Is the entire call recorded or only when someone is talking?
- The entire call is recorded.
The conference guide does not make the call. What is the problem?
- There can be two reasons for this: The conference guide's settings. Check or update the following:
  1. Click on Menu
  2. Click on Conference Guide and then choose Settings
  3. Check/update the setting for request, return and conference. Different PBXs and countries have different flash times You must have the right settings for the conference guide to function properly.
  
  Check or update the following:
  1. Click on Menu
  2. Click on Setting and then choose Flash/R 3. The predefined Flash time is highlighted. Below are the recommended settings. Flash times: 100 ms – Scandinavia, Europe, Siemens Enterprise Communications HiPath 300 ms – Germany, France, and Israel 500 ms – USA.

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.

Brand	Model	Command	Notes
Aastra	BusinessPhone	F3
Avaya	IP Office	*47
Avaya	Integral 55	F4	Add-on conference must be active
Ericsson	MD110	3
Euro	Generis	F63
Philips	Sopho IS3000	F	F*3 for new line
Samsung	Office Serv 500	46
Unify/Siemens	HiCom Office	*5
Unify/Siemens	HiPath	*3	or F3 or 53
