Can we use EM7411 as VoLTE module?

1

Hi,
We are planing to use EM7411 to develop VoLTE application, can this module be used?
And some questions need you help?

  1. is there an API to do AKA authentication?
  2. or can we use pure AT commands to do AKA authentication?
  3. Do the CSIM is supported in this module? I plan to use CSIM to do AKA authentication, but always received “ERROR”, if this module support this command, could you give me a example for reference, it’s better if you can provide how to implement 3GPP TS 31.102 7.1.2 .

Thanks.
