Calling
If your multi-party call is not answered
Press the R key followed by the 1 key to
return to the first call.
Note: The availability and function of the multi-party feature can vary from
country to country but also depend on the PBX to which the Konftel 100 is
connected. If you want to connect multiple participants we recommend you use
a telephone meeting service. If you have questions regarding availability, please
contact your dealer.
If the R key does not work
The requirements for the operation of the R key vary between PBXs and from
country to country. Konftel 100 therefore lets you program the R-pulse time so
that it works with most PBXs on the market.
Programming the R key (default setting = 2)
Hold down the R key for three seconds until the green
LEDs flash and you hear three short beeps.
1–6...
Enter the value for the R-pulse. The default setting is 2.

your PBX/country.
