How do I connect a conference call with my Konftel?
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.
