Electronic device for routing short-range radio signals, the device comprising: - one receiver/transmitter of short-range radio signals configured to: • receive from a mobile electronic device a first short-range radio signal (S1_r_sd) carrying data indicating an incoming voice call request and the caller's phone number and transmit a signal (S_bo_int) carrying a first message indicating the incoming voice call request and the caller's phone number; • receive a signal (S_bi_int) carrying a second message indicating an accepted incoming voice call and transmit towards the mobile electronic device the first short-range radio signal (S1_r_sd) carrying data indicating the accepted incoming voice call; • receive from the mobile electronic device the first short-range radio signal (S1_r_sd) carrying audio data of a voice communication and transmit the signal (S_bo_int) carrying the first message including the audio data of the voice communication; • receive the signal (S_bi_int) carrying the second message including the audio data of the voice communication and transmit to an audio player device a second short-range radio signal (S2_r_sd) carrying said audio data of the voice communication; - a processing unit bidirectionally connected to the short-range radio signals receiver/transmitter, the processing unit being configured to: • receive the signal (S_bo_int) carrying the first message indicating the incoming voice call request and the caller's phone number and transmit (S_bo) to an images display device a third message indicating the caller's phone number; • receive from a selector a fourth message (S_bi) indicating the accepted incoming voice call and transmit the signal (S_bi_int) carrying the second message indicating the accepted incoming voice call; • receive the signal (S_bo_int) carrying the first message including the audio data of the voice communication and transmit the signal (S_bi_int) carrying the second message including the audio data of the voice communication. - one receiver/transmitter of short-range radio signals configured to: • receive from a mobile electronic device a first short-range radio signal (S1_r_sd) carrying data indicating an incoming voice call request and the caller's phone number and transmit a signal (S_bo_int) carrying a first message indicating the incoming voice call request and the caller's phone number;
