Hello,
We purchased a BG96 USB dongle (ID 2c7c:0296 Quectel Wireless Solutions Co., Ltd. BG96 CAT-M1/NB-IoT modem) and would like to do voice calls with it.
After resetting the modem with
usb_modeswitch -v 0x2c7c -p 0x0296 -V 0x2c7c -P 0x0296 -m "0x01" -R
chmod -R a+rwx /dev/ttyUSB2
stty -F /dev/ttyUSB2 9600
and then connecting to /dev/ttyUSB2, i do 'ATZ' and 'AT+CPIN="XXXX"' and it reports 'OK'. We can send and receive SMS-s with it. However, when i try to do 'ATD36XXXXXXXXX;' (with or without the semicolon), all it reports is 'ERROR'. Also, if we try to call the dongle, then the phone which calling it beeps three times and then simply disconnects and there is not any kind of report from the dongle. (My brother says, the call is being redirected.)
We have bought it on Aliexpress and it’s page says, it supports voice calls: https://www.aliexpress.com/item/1005005855661231.html?spm=a2g0o.order_list.order_list_main.11.4fe618020fgczY
