Code c# receive incoming calls and play audio Module GSM Quectel M26 16 port

Hello.

I am using Modlue GSM Quectel M26 type 16 port.
Need to support c# code: call and play audio with keypress confirmation; receive incoming calls and play audio

limited by the size of RAM &ROM , the M26 does not support C# code , you can load C# code in external MCU , and us M26 as communication function only .

Thanks for your understanding
