The BM818-A1 modem I have with September 2021 firmware does not make VoLTE calls no matter how hard I try even with the experimental .deb tools provided on github it only makes calls over 2G. I understand this is probably extremely hard to accomplish but any sort of transparency would be great to show basic items like VoLTE being taken care of even though VoLTE is handled by the m.2 modem. Do any AweSim customers have VoLTE working for them? Does the 2019 BM818 firmware work but not the 2021 BM818-A1 firmware doesnt, for VoLTE to function? If the 2019 firmware does work for VoLTE can someone point me in the right direction so I can flash it.
