TFIE headset operation
From Zenitel Wiki
The TFIE Industrial IP Stations TFIE-1 and TFIE-2 support the use of headset.
Zenitel offers the TA-22B Cable/plug box and the headset AK5850HS, but you can also choose to use a 3rd-party headset.
The TFIE has a pinheader connector J8 for headset speaker, mic and PTT.
Modes of operation
There are two modes of operation. The mode is set from the stations web interface.
Turbine Headset
In this mode the audio is by default routed to the speaker and mic of the front panel of the TFIE station. Audio is also routed to the headset speaker in parallel. Headset mic is disabled.
By pressing the headset PTT button, or the "Speaker" button on the front panel (TFIE-1 only), the audio is routed to the headset, the headset mic is enabled, and the audio in the front panel is muted.
When the conversation is ended, the audio is automatically routed back to the front panel, and the headset mic is disabled.
Turbine Headset w/autodetect
In this mode the audio is routed to the headset as soon as the headset is connected. Audio in the front panel is muted. The front panel will remain muted as long as the headset is connected.
Note: The auto-detect feature is tested with the headsets that Zenitel supplies. The detection might not work with any type of 3rd party headset.
