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??
