title: How do I play a prerecorded audio using GSM Sim800a with ESP8266 and Arduino IDE
body: <p>I am writing a DTMF based code that whenever I call a specified person using my GSM Module i.e. SIM800A and ESP8266 (NodeMCU v2) using Arduino IDE, person will hear an audio file about the DTMF Tones available.</p>
  <p>But  while searching the internet on this idea I got this command to play a prestored amr file in the GSM Module</p>
  <blockquote>
  <p>AT+CREC=4,&quot;C:\User\9.amr&quot;,0,90</p>
  </blockquote>
  <p>Please someone help me by either telling how I can upload the amr file to the internal memory of my GSM Module,</p>
  <p>OR</p>
  <p>How I can access the audio file from the internal memory of my ESP8266 and play it.</p>
  <p>A small help from your busy schedule is also really appreciated.</p>
