If your dialing plan foresees the use of hunt groups, these still have to
be entered into the configuration manually (’Hunt groups with call

This is how you configure your telephones and
terminal equipment
Apart from configuring the LANCOM Business-VoIP-Router itself, some
setting up of the terminal equipment is also necessary to ensure that it
remains fully functional in the telephone network.
3.3.1
Analog telephones
Analog telephones use the Flash key (F key) to control certain functions.
Pressing the F (or Flash-) key causes the line to be interrupted briefly. The PBX
detects this flash and interprets any following tones not as numbers but as
control signals intended for the PBX.
The duration of this interruption plays a significant role in the triggering of
control sequences. LANCOM Business-VoIP-Routers expect a "short" flash of
80 to 150 ms. Many devices are preset to use the "long" flash of 170 to
310 ms.
For this reason you should set your analog telephone to use the short flash.
Many devices allow this value to be adjusted in a menu under
Settings
PBX
Flash
. If your model allows an explicit flash duration to be defined,
set the flash-time value to 100 ms.
If necessary, please refer to the documentation for your device for
information on these settings.
3.3.2
ISDN telephones
The use of ISDN telephones requires the configuration of the MSN in the
terminal device. To make use of PBX functions in the LANCOM Business-VoIP-
Router, the parameters "ECT" and "Keypad" have to be checked and/or set.
If necessary, please refer to the documentation for your device for
information on these settings.
