+QIMSCFG documentation

Could I please have documentation for the above AT command? Many of my Quectel modems respond to the AT+QIMSCFG=? command, eg the RM500Q-AE:

AT+QIMSCFG=?
+QIMSCFG: "ims_enable",<value>,<subs_id>,<volte_status>
+QIMSCFG: "impi"
+QIMSCFG: "impu"
+QIMSCFG: "domain"
+QIMSCFG: "authenticate",<context>,<data>
+QIMSCFG: "user_agent",<UA>
+QIMSCFG: "qirep",<value>

I have sent it to you,pls check

Thank you kindly, much appreciated.

Could you please send me this documentation as well? Thanks!

Actually the reason I asked for this is an issue I’m having with a different module.

I’m testing EM12-G with firmware EM12GPAR01A21M4G_01.300.01.300 .
I’m trying a VoLTE call, but I don’t get any RING message on the AT port.
Using the documentation you sent me I got:
AT+QIMSCFG=“qirep”,0,1,0,6,1,1,0,1

So voice is supported over IMS.
But I get no RING when I call the module, and get NO CARRIER message if try to call from the module.
May i’m missing something special, or is a problem of the firmware that i’m running?

Thanks in advance
