I wonder if mdm6600 is the i2s master during the voice call?

Then using the n_gsm ts 27.010 uart mux, I dial:

./ngsm-rw 1 "AT+CFUN=1"		# connect to network
U0001+CFUN:OK
./ngsm-rw 2 "AT+CMUT=0"		# unmute speaker over ch2, do this over qmi?
U0001+CMUT:OK
./ngsm-rw 1 "ATD#123"		# dial number
U0001D:OK

And I do hear a voice talking over the speakerphone :) Sorry have not tested the
mic yet..
