require('agi').createServer(function(context) {
  //context is a new instance of agi.Context for each new agi session
  //immedately after asterisk connects to the node process
  context.on('variables', function(vars) {
    console.log('received new call from: ' + vars.agi_callerid + ' with uniqueid: ' + vars.agi_uniqueid);
  });
}).listen(3000);

new agi.Context(stream)

Constructor to create a new instance of a context. Supply a readable and writable stream to the constructor. Commonly stream will be a net.Socket instance.

context.exec(command, [args], [callback])

Dispatches the EXEC AGI command to asterisk with supplied command name and arguments. callback is called with the result of the dispatch.

context.exec('ANSWER', function(err, res) {
  //the channel is now answered
});

context.exec('RecieveFax', '/tmp/myfax.tif', function(err, res) {
  //fax has been recieved by asterisk and written to /tmp/myfax.tif
});

context.hangup([callbac])
