Today found this explanation: Before the call is terminated, the 
received.wav file doesn't have any header ! For me to hear it in nearly real 
time, a right command can be that one :
$ aplay -f S16_LE -c 1 -r 8000 -t wav --buffer-size=96 /tmp/received.wav &

Happy end, but artificial method, isn't it ?
