Class ControlStreamFileCommand

java.lang.Object

org.asteriskjava.fastagi.command.AbstractAgiCommand

org.asteriskjava.fastagi.command.ControlStreamFileCommand

All Implemented Interfaces:

Serializable, AgiCommand

public class ControlStreamFileCommand
extends AbstractAgiCommand

Plays the given file, allowing playback to be interrupted by the given digits, if any, and allows the listner to control the stream.

If offset is provided then the audio will seek to sample offset before play starts.

Returns 0 if playback completes without a digit being pressed, or the ASCII numerical value of the digit if one was pressed, or -1 on error or if the channel was disconnected.

Remember, the file extension must not be included in the filename.
