VoLTE supports on BG-77

Dear support,

We are evaluating the BG-77 module for one IoT product and its supports of VoLTE.
I read in the datasheet that BG-77 supports for LTE Cat M1 only. Fine.

We have a working hardware (data, SMS… works on it) and we are testing its function including VoLTE.
Testing AT commands (AT+QCFG=“ims”), we receive some error.
My questions then are:

  • Does BG-77 need a specific version of the firmware to have VoLTE working ?
  • Is there any application note available fo VoLTE ?

Thank you very much in advance and best regards,
Dominique

BG77 Series are support VoLTE and I will send you this application note via email.

Hi Mikey,

Well received the application note.

What about my last question about any mandatory firmware version ?

Thank you, bfn,
Dom

Hi Dominique,
The BG77 normal version will support VoLTE.

Hi Mikey,

Is the version LB needed ?
I heard that fom some other info.

Thx, bfn,
Dom
