SimpleIVR
=========
Basic IVR using Sim900 module + AT commands + c#.net
Usage
- Connect Sim900 GSM module to PC via RS232 cable
- Power up GSM module, in my case i used 12 V 1 Amp adapter as power source. (You's might differ)
- Run SimpleIVR.exe program
This Exe connects to Com1 port and checks if there is a RING on Serial / GSM (every 1 second) and if there is a Incoming call (RING)
Then answers the call issuing ATA command.
The analog speaker out from PC acts as MIC input for GSM.
A text to speech module (inside Program.cs) provides the necessary audio.
After completion of Voice message call is disconnected using ATH command.
