Hello,
I am working on a project having 8051 controller and SIM900.
In this i have to make call to mobile numbers and send a voice msg. I am using apr2060 voice ic for this purpose in which i have recorded a voice msg.
Now problem i am facing is that the voice msg received over mobile contains too much noise. I have connected the voice_output pin of apr2060 with Mic+ and Mic- points of sim900. When i connect a speaker on voice_output pin of apr2600 the audio msg is very clear and seems very less noise.
Please suggest me a solution.
