[Moved] SIM900 with Arduino plays a voice file

[a.s8]

Hey guys..

I'm in a project that uses Arduino UNO + SIM900 to receive and make a call. I want to make the SIM900 pick up the call and then plays a voice file to the user like an answer machine.

I know how to receive and pick up the call, MY PROBLEM is in the voice file. HOW TO PLAY A VOICE FILE IN SIM900 DURING THE CALL? So the SIM900 picks up the call and then plays the voice note like: " Welcome this is SIM900, How can I Help you?"

PLEASE help me

You'll need an MP3 shield or a separate player to make the sound, plug it into the microphone port of the SIM900, and control from the Arduino.
Arduino itself is unlikely to be capable of decoding and producing sound on it's own.
