Is my VoLTE working?
Hi, I followed all the instructions I could find to get VoLTE working. My carrier "Consumer Cellular" uses AT&T network which is soon totally disabling 3G so I must get VoLTE working. However I'm not sure if it is working. I need help understanding it.

I have Manjaro CE with Phosh.

I reached the carrier support and they succesfuly detected the modem model and enabled something on their end to allow VoLTE.

I followed the VoLTE steps on the main PinePhone wiki page.

+QCFG: "ims",1,1


The 4G indicator shows in the UI. To test, I called my wife.

#Start call to my wife:

[root@manjaro-arm ~]# echo 'AT+CLCC' | atinout - /dev/EG25.AT -
+CLCC: 2,1,0,1,0,"",128
+CLCC: 1,1,0,1,0,"",128
+CLCC: 3,0,0,0,0,"4436179824",129,"Andrea"
+CLCC: 4,1,0,1,0,"",128


#Hang up:

[root@manjaro-arm ~]# echo 'AT+CLCC' | atinout - /dev/EG25.AT -
+CLCC: 2,1,0,1,0,"",128
+CLCC: 1,1,0,1,0,"",128


[root@manjaro-arm ~]# echo 'AT+QNWINFO' | atinout - /dev/EG25.AT -
+QNWINFO: "FDD LTE","310410","LTE BAND 2",700


Elsewhere I have read that the fourth value of AT+CLCC tells you whether the voice is carried by VoLTE. The Quectel AT command reference says ony this about it:

<mode>Bearer/tele service
0: Voice
1: Data
2: FAX

However the line with my wife's phone number has a 0 in that position. Still I wonder, with all the other symptoms lining up??
This example would suggest so

You're also registered on IMS.

If your phone stays on 4G then yes, it's VoLTE for sure, if it drops to 3G (or 2G) for the call, then no.

You can also check whether or not you're on 4G during the call (rather than after) using

mmcli -m any --command='AT+QNWINFO'

You might add this to the other thread if it's confirmed.
