The phone is not able to detect a headset is connected via the analog headset port or the USB port.
What if I still get the message even though a headset is present?
You may override detection by setting the switch in the audio preferences (Settings → Preferences → Audio)
Alternatively the setting
may be set to off (default is on)
When is deactivation of detection necessary?
The phone is only able to detect
- directly connected headsets on the analog port,
- headsets that use the Snom EHS Advanced V2.0 and
- USB headsets.
Headsets that have a base but are directly connected using the analog port and not using the Snom EHS Advanced V2.0 many not be correctly detected.
In this case the detection needs to be switched off to use the headset.
