Voice call recording on M26 (Revision M26FAR03A04_TTS) and firmware request

IoT Modules GSM Module

Dear Quectel Support Team,

I am working with a Quectel M26 module and need to implement voice call recording.

My module details are:

  • Model: M26
  • Hardware Revision: M26FAR03A04_TTS

I have tried to use the AT+CAUDIOSURVEY command for recording, but it returns “CME ERROR: 100”. The AT+CLAC command also fails with the same error, which suggests limited functionality in my current firmware version.

My questions are:

  1. Is voice call recording supported on my hardware revision (M26FAR03A04_TTS)?
  2. If yes, which AT commands should I use (AT+CAUDIOSURVEY or others)?
  3. Could you please provide the latest available firmware for my module that supports audio recording features?

I would greatly appreciate any documentation (like Application Notes for audio features) and firmware updates that could enable this functionality.

Thank you for your assistance!
