The present invention relates to a method for calibrating a hands-free system, the hands-free system comprising a hands-free unit and a mobile phone, the method comprising the following steps:
- setting up a connection between the hands-free system and a distant terminal via a mobile telephony network of the mobile phone,
- transmitting a predetermined test signal from one of the hands-free system and the distant terminal to the other of the hands-free system and the distant terminal, the predetermined test signal being provided in both the hands-free system and the distant terminal as reference test signal,
- comparing the received test signal to the reference test signal stored in the other of the hands-free system and the distant terminal, and
- determining the calibration parameters of the hands-free system in accordance with the comparison.
