Use Asterisk to record prompts

You don’t need to be a professional audio engineer to record sound prompts for your auto attendant system. Asterisk features an application called Record that enables you to record your own custom prompts. This application plays a beep, and then begins recording audio until the caller presses the hash key. The recorded sound is then saved to the specified file.

Write the following code in the dialplan:

[local]
exten => 700,1,Answer()
 same => n,Record(our_greeting.wav)
 same => n,Wait(4)
 same => n,Playback(our_greeting)
 same => n,Hangup

When you dial the 700 extension, you should hear a beep. Record your greeting and press the hash key (#) when you are done. After 4 seconds you should hear your recorded message. Notice how the application Record takes the entire filename as its argument – the extension specifies the format of the recording (WAV in our case). The Playback application also takes the filename as the argument, but without the extension.
