Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Readme

Getting Started

1. Usage

npm install --save agi-node

var AGIServer = require('agi-node').AGIServer;
//var AsyncAGIServer = require('agi-node').AsyncAGIServer;
//var conn = new require('asterisk-manager')(5038, 'localhost', 'asterisk', 'astpass', true);

function fakeCallback(param, callback) {
  setTimeout(function () {
    callback(null, param);
  }, 2000);
}

function testScript(channel) {
  console.log('Script got call %s -> %s', channel.request.callerid, channel.request.extension);

  var answerReply = channel.answer();
  console.log('ANSWER', answerReply);

  console.log('CHANNEL STATUS', channel.channelStatus());
  console.log('GET UNIQUEID', channel.getVariable('UNIQUEID'));
  console.log('GET JUNK', channel.getVariable('JUNK'));

  console.log('beeping in 2 seconds');
  channel.streamFile(fakeCallback.sync(null, 'beep'));


  console.log('PLAYBACK', channel.streamFile('conf-adminmenu'));
  console.log('PLAYBACK', channel.streamFile('conf-adminmenu'));
}

/* Async AGI Server */
// conn is an asterisk-manager connection
//var server = new AsyncAGIServer(script, conn);

/* AGI Server */
var server = new AGIServer(testScript, 4573);
  • AGIServer constructor receives two parameters: a mapper and a port. If the mapper is a function it will execute that as an AGI script. If it is an object it maps script names from AGI URL to generator functions. Example: {hello: helloScript} will map agi://agi_host/hello to helloScript. The port is the AGI standard listening port (default 4573)
  • AsyncAGIServer receives two parameters: a mapper and an AMI connection (established through asterisk-manager)
  • The script should exit at the very end. That means that all async operations (e.g. database lookups) need to be done using sync library. This is a dependency of agi-node and the script is executed inside a fiber, so callbacks can be put in "sync" mode (see fakeCallback example above and sync library itself at https://www.npmjs.com/package/sync).

2. Channel API

2.1 Channel.request

This property is an object that maps all the AGI initialization variable without the agi_ prefix (e.g. agi_calleridname becomes channel.request.calleridname). Here's a list of all of these variables:

  • agi_request - The filename of your script
  • agi_channel - The originating channel (your phone)
  • agi_language - The language code (e.g. "en")
  • agi_type - The originating channel type (e.g. "SIP" or "ZAP")
  • agi_uniqueid - A unique ID for the call
  • agi_version - The version of Asterisk (since Asterisk 1.6)
  • agi_callerid - The caller ID number (or "unknown")
  • agi_calleridname - The caller ID name (or "unknown")
  • agi_callingpres - The presentation for the callerid in a ZAP channel
  • agi_callingani2 - The number which is defined in ANI2 see Asterisk Detailed Variable List (only for PRI Channels)
  • agi_callington - The type of number used in PRI Channels see Asterisk Detailed Variable List
  • agi_callingtns - An optional 4 digit number (Transit Network Selector) used in PRI Channels see Asterisk Detailed Variable List
  • agi_dnid - The dialed number id (or "unknown")
  • agi_rdnis - The referring DNIS number (or "unknown")
  • agi_context - Origin context in extensions.conf
  • agi_extension - The called number
  • agi_priority - The priority it was executed as in the dial plan
  • agi_enhanced - The flag value is 1.0 if started as an EAGI script, 0.0 otherwise
  • agi_accountcode - Account code of the origin channel
  • agi_threadid - Thread ID of the AGI script (since Asterisk 1.6)

2.2 Channel methods

  • answer()

Answers the channel

  • channelStatus()

Returns the current channel status (see http://www.voip-info.org/wiki/view/channel+status)

  • continueAt(context, extension, priority)

Sets the point in the dialplan to continue the call after the AGI script is done. extension is optional and, if missing, is set the current channel extension. priority is optional and, if missing, is set to 1.

  • exec(applicationName, applicationParameters)

Executes the requested dialplan application with parameters

  • getData(file, timeout, maxDigits)

Reads DTMF input from user. Plays the file prompt. Times out at timeout milliseconds and allows up to maxDigits to be read. It can be ended with #.

  • getVariable(variableName)

Reads the specified variable value on the current channel. Returns null if variable does not exist.

  • noop()

Does nothing.

  • recordFile(file, format, escapeDigits, timeout, silenceSeconds, beep)

Records the current channel in file using format. Recording can be stopped using one of the escapeDigits or after silenceSeconds. If beep is true, a beep sound is played before recording is started.

  • setContext(context)

Sets the context to continue at after leaving the script.

  • setExtension(extension)

Sets the extension to continue at after leaving the script.

  • setPriority(priority)

Sets the priority to continue at after leaving the script.

  • setVariable(variable, value)

Sets the specified variable to the desired value.

  • streamFile(file, escapeDigits)

Plays the specified file. Playback can be stopped using one of the (optional) escapeDigits.

  • hangup()

Hangs up the current channel.
