Hi,
I am stuggeling with getting a IoT device with Quectel EC21-e to call over VoLTE.
I have searched thru forum and google to find any info, but i cannot find “the solution”.
So I have a IoT unit that supports VoLTE and I have a Sim card with VoLTE supported.
I have testet on a Teltonika 240 with Meiglink chip and this is working.
I guess i have to set some parameters on my IoT device to get VoLTE working.
Do anyone have any ideas how to get this working?
AT+CGDCONT? - shows
+CGDCONT: 1,“IPV4V6”,“”,“0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0”,0,0,0,0
+CGDCONT: 2,“IPV4V6”,“telenor.smart”,“0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0”,0,0,0,0
I tryed to insert those manually:
+CGDCONT: 1,“IPV4V6”,“”,“0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0”,0,0,0,0
+CGDCONT: 2,“IPV4V6”,“ims”,“0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0”,0,0,0,0
+CGDCONT: 3,“IPV4V6”,“SOS”,“0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0”,0,0,0,0
But this is not working, and its gone after reboot.
I was thinking i was supposed to see something with IMS?
AT+QNWINFO+QNWINFO: “FDD LTE”,“24201”,“LTE BAND 3”,1450
AT+QCFG=“nwscanmode”,3
AT+COPS?
