VoLTE on EG25-G

IoT Modules LTE Standard Module
1

Hello,

Is VoLTE supported on the EG25-G module?
The module we are testing has firmware revision number EG25GGBR07A07M2G.
Can this firmware support VoLTE?
Do we need to update the firmware?

Using the AT+QCFG=“ims” request, we got the following response:
+QCFG= “ims”,1,0
This means that VoLTE is disabled, correct?

Using the AT+QMBNCFG request, we got the following response:

+QMBNCFG: “List”,0,1,1,“ROW_Generic_3GPP”,0x0501081F,201901141
+QMBNCFG: “List”,1,0,0,“VoLTE-ATT”,0x0501033C,201905161
+QMBNCFG: “List”,2,0,0,“hVoLTE-Verizon”,0x05010141,201907121
+QMBNCFG: “List”,3,0,0,“Sprint-VoLTE”,0x05010205,201908141
+QMBNCFG: “List”,4,0,0,“Commercial-TMO_VoLTE”,0x05010505,201811231
+QMBNCFG: “List”,5,0,0,“Telus-Commercial”,0x05800C60,201812141
+QMBNCFG: “List”,6,0,0,“Commercial-SBM”,0x05011C18,201904021
+QMBNCFG: “List”,7,0,0,“Commercial-DT”,0x05011F1C,201905311
+QMBNCFG: “List”,8,0,0,“Reliance-VoLTE”,0x05011B38,201908151

Thanks.

Hi Patrik
Of course it is supported. You can use AT+QCFG=“ims”,1 to restart the module, and query AT+QCFG=“ims” again to use the volte function.
Best wishes

When I tried AT+QMBNCFG, I got ERROR back.

Does that mean my provider doesn’t support VoLTE?

I think the commands you’re looking for are:

AT+QMBNCFG="List"
AT+QMBNCFG="AutoSel"
