EC25-J DCM-variant: AT+QAUDPLAY/AT+VTS fail during VoLTE call - Need Standard Firmware for R06

IoT Modules LTE Standard Module

Hello,

Thank you for your previous reply. To clarify my request and avoid confusion with other models:

I am focused solely on the EC25-J R06 series (EC25JFAR06A04M4G_DCM). I do not need support for the R02 series anymore.

My goal is to play a WAV file from UFS to a VoLTE call using the AT+QAUDPLAY or AT+QAUDRD command. Currently, these commands and AT+VTS (DTMF) return ERROR on this DCM-variant module.

I understand that a cross-baseline upgrade is not officially suggested, but since the DCM-variant locks these essential audio features, I cannot proceed with my project. I am willing to take all risks of flashing at my own responsibility.

Could you please provide the latest Standard (Global/J-model) Variant firmware for the R06 series, along with QFlash and USB Drivers?

I need the standard version for the EC25-J (Japan model) specifically to ensure hardware compatibility and compliance while enabling the UAC and audio playback features.

My email: [fmtk2112@gmail.com]

Thank you for your understanding and continued support.

Best regards,
