Troubleshooting guide
Remedy
Connect the cable.
Connect the cable to the interface
marked ISDN.
For information on the correct
type of connector and cable, refer
to the installation manual.
Make sure the call type used for
calls to the terminal is selected in
the web interface. Access the web
interface and select SETTINGS >
ISDN. Then select the call type for
incoming calls.
Use another service. You may still
use the ISDN interface on the
terminal, but only Standard voice
and 3.1 kHz Audio are available.
If the Mute function should not be
activated, deactivate it from the
external device.
