Found it! Here's what I need to do over n_gsm: ngsm 1 "AT+CFUN=1" ngsm 1 "AT+CFUN?" ngsm 2 "AT+EACC=3,0" # enable mic ngsm 2 "AT+CLVL=4" # set speaker volume ngsm 2 "AT+CMUT=0" # unmute mic ngsm 1 "ATD${number}" ngsm 1 "AT+CLCC" # list current calls ngsm 2 "AT+NREC=1" # enable noise cancellation ngsm 1 "AT+SCRN=0" # ??? not sure if this does anything while [ 1 ]; do date ngsm 1 "AT+CLCC" sleep 10 done So speaker phone call works just fine, I just tested with a human at the other end :) Hmm let's hope all those also translate to some qmi calls.
