Telephone Interface Unit And A Method Of Configuring Headset System To Telephone Device

A method of setting up a headset system to a telephone device, the headset system comprising a headset and a telephone interface unit, wherein the headset is connectable to the telephone interface unit configured to interconnect the telephone device and the headset, the method comprising the steps of

• receiving in the telephone interface unit, telephone configuration information from the telephone device,
• selecting in a processor a specific pre-programmed permutation setting based on the received telephone configuration information,
• controlling the processor to switch a switching unit in the telephone interface unit to connect a headset transmit signal line and a headset receive signal line to a telephone transmit signal line and a telephone receive signal line, in accordance with the specific pre-programmed permutation setting.

A self-configuring headset system, the headset system comprising a headset and a telephone interface unit, the telephone interface unit comprising

• a switching unit configured to switch at least a headset transmit signal line and a headset receive signal line to a telephone transmit signal line and a telephone receive signal line, respectively, and
• a processor being pre-programmed with one or more telephone device permutation settings,
• wherein the processor is configured to receive, from the telephone device, telephone configuration information on the basis of which a specific permutation setting is selected among the one or more pre-programmed permutation settings, the processor being configured to control the switching unit to switch at least the headset transmit signal line and the headset receive signal line to the telephone transmit signal line and the telephone receive signal line, respectively, according to the specific permutation setting.
