Analog Connection
Switching Busy Tone Detection (Incoming) for End of Call On/Off
This is necessary for detecting the end of the call connection and to enable the automatic hang-
up of an ISDN telephone.
Note: Deactivate this setting if interference on the external PBX line is inter-
preted as a busy signal and interrupts calls. In this case, the call needs to be
ended on the PBX by the subscriber by hanging up.
Switching this on/off can be done as follows:
• Via the configuration manager
Requirements:
– External analog port (only COMpact 3000 analog)
– Configuration manager, opened with sufficient authorization
– Expert view (click )
– Configured prefixes (country prefix and local area code)
1. Open the page CONFIGURATION > External numbers.
2. In the list field at the top, select the analog connection.

interpreted as a busy signal.
