The purposes of this program / Script is to test the recording function and call back (Notification function) of a voice-mail system.
The program / Script will call a local phone number wait until it hears audio then send a DTMF tone (#2) wait for the BEEP and play a out.wav file that is 15 sec long then hang up. It will then wait for X amount of time for a return call.
If it receives a return call it will answer the call and play in.wav then hang-up and wait X sec and start over with a new call.
If it DOES not receive a call it will check to see how many times (X)( Failed call back) it must wait until it calls a 2nd (DOWNED SYSTEM) phone number then wait for audio/voice and play help.wav file to let us know that the system has not responded.
