asterisk-manager-ts

A modern, fully-typed TypeScript library for interacting with the Asterisk Manager Interface (AMI). Built from the ground up with TypeScript, this library provides a robust, event-driven interface for managing Asterisk PBX systems.

Features

• 🎯 Full TypeScript Support - Complete type definitions for all AMI operations
• 🔄 Event-Driven Architecture - Built on Node.js EventEmitter with proper typing
• 🔐 Authentication Management - Automatic login and session handling
• 🔌 Auto-Reconnection - Configurable automatic reconnection with exponential backoff
• 📡 Action Queue - Intelligent action queuing when not authenticated
• 🛡️ Error Handling - Comprehensive error handling and debugging support
• 📦 Zero Dependencies - Only requires Node.js built-in modules
• 🏗️ Clean API - Simple, intuitive interface for all AMI operations

Installation

npm install asterisk-manager-ts

Note: This package includes TypeScript definitions built-in. No need to install @types/asterisk-manager.

Quick Start

TypeScript

import Manager from "asterisk-manager-ts";

const ami = new Manager(5038, "localhost", "admin", "secret", true);

ami.on("connect", () => {
  console.log("Connected to Asterisk Manager Interface");
});

ami.on("managerevent", (event) => {
  console.log("AMI Event:", event);
});

// Execute an action
ami.action(
  {
    action: "Status",
  },
  (error, response) => {
    if (error) {
      console.error("Action failed:", error);
    } else {
      console.log("Status response:", response);
    }
  }
);

JavaScript (CommonJS)

const Manager = require("asterisk-manager-ts");

const ami = new Manager(5038, "localhost", "admin", "secret", true);

ami.on("connect", () => {
  console.log("Connected to Asterisk Manager Interface");
});

API Documentation

Constructor

new Manager(port?: number, host?: string, username?: string, password?: string, events?: boolean)

• port - AMI port (default: 5038)
• host - Asterisk server hostname or IP
• username - AMI username
• password - AMI password
• events - Whether to receive events (default: false)

Methods

connect(port: number, host: string, callback?: ConnectionCallback): void

Establishes a connection to the AMI.

ami.connect(5038, "192.168.1.100", (error) => {
  if (error) {
    console.error("Connection failed:", error);
  } else {
    console.log("Connected successfully");
  }
});

login(callback?: ManagerCallback): void

Authenticates with the AMI using provided credentials.

ami.login((error, response) => {
  if (error) {
    console.error("Login failed:", error);
  } else {
    console.log("Logged in successfully");
  }
});

action(action: ManagerAction, callback?: ManagerCallback): string

Executes an AMI action and returns the action ID.

const actionId = ami.action(
  {
    action: "Originate",
    channel: "SIP/1001",
    context: "default",
    exten: "1002",
    priority: 1,
  },
  (error, response) => {
    if (error) {
      console.error("Originate failed:", error);
    } else {
      console.log("Call originated:", response);
    }
  }
);

keepConnected(): void

Enables automatic reconnection with exponential backoff.

ami.keepConnected();

disconnect(callback?: () => void): void

Disconnects from the AMI.

ami.disconnect(() => {
  console.log("Disconnected from AMI");
});

isConnected(): boolean

Returns the current connection status.

if (ami.isConnected()) {
  console.log("AMI is connected");
}

Events

The library extends Node.js EventEmitter and emits various events:

Connection Events

ami.on("connect", () => {
  console.log("Connected to AMI");
});

ami.on("close", () => {
  console.log("Connection closed");
});

ami.on("error", (error) => {
  console.error("Connection error:", error);
});

AMI Events

// All AMI events
ami.on("managerevent", (event) => {
  console.log("AMI Event:", event.event, event);
});

// Specific events (case-insensitive)
ami.on("newchannel", (event) => {
  console.log("New channel:", event.channel);
});

ami.on("hangup", (event) => {
  console.log("Channel hung up:", event.channel);
});

// User events
ami.on("userevent-myevent", (event) => {
  console.log("Custom user event:", event);
});

Action Responses

// All action responses
ami.on("response", (response) => {
  console.log("Action response:", response);
});

// Specific action response by ID
ami.once(actionId, (error, response) => {
  if (error) {
    console.error("Action failed:", error);
  } else {
    console.log("Action succeeded:", response);
  }
});

TypeScript Types

The library provides comprehensive TypeScript definitions:

Core Interfaces

interface ManagerOptions {
  port: number;
  host: string;
  username: string;
  password: string;
  events: boolean;
}

interface ManagerAction {
  action: string;
  actionid?: string;
  [key: string]: unknown;
}

interface ManagerEvent {
  event?: string;
  response?: string;
  actionid?: string;
  content?: string;
  [key: string]: unknown;
}

type ManagerCallback = (
  error?: ManagerEvent | Error | null,
  response?: ManagerEvent
) => void;

Specific Action Types

interface LoginAction extends ManagerAction {
  action: "login";
  username: string;
  secret: string;
  event: "on" | "off";
}

// Define your own action types
interface OriginateAction extends ManagerAction {
  action: "Originate";
  channel: string;
  context: string;
  exten: string;
  priority: number;
  timeout?: number;
  callerid?: string;
}

Common Examples

Making a Call

ami.action(
  {
    action: "Originate",
    channel: "SIP/1001",
    context: "default",
    exten: "1002",
    priority: 1,
    timeout: 30000,
    callerid: "Test Call <1001>",
  },
  (error, response) => {
    if (error) {
      console.error("Failed to originate call:", error);
    } else {
      console.log("Call originated successfully:", response);
    }
  }
);

Monitoring Channel Events

ami.on("newchannel", (event) => {
  console.log(`New channel created: ${event.channel}`);
});

ami.on("hangup", (event) => {
  console.log(`Channel ${event.channel} hung up. Cause: ${event.cause}`);
});

ami.on("newstate", (event) => {
  console.log(
    `Channel ${event.channel} changed state to ${event.channelstatedesc}`
  );
});

Getting System Status

ami.action({ action: "Status" }, (error, response) => {
  if (error) {
    console.error("Failed to get status:", error);
  } else {
    console.log("System status:", response);
  }
});

Listing Active Channels

ami.action({ action: "CoreShowChannels" }, (error, response) => {
  if (response?.response === "follows") {
    console.log("Active channels:");
    console.log(response.content);
  }
});

Error Handling

The library provides comprehensive error handling:

ami.on("error", (error) => {
  console.error("AMI Error:", error.message);

  // Handle different error types
  if (error.message.includes("ECONNREFUSED")) {
    console.log("Asterisk server is not running or AMI is disabled");
  }
});

// Action-specific error handling
ami.action({ action: "InvalidAction" }, (error, response) => {
  if (error) {
    console.error("Action error:", error);
    // error will contain the error response from Asterisk
  }
});

Auto-Reconnection

Enable automatic reconnection to handle network issues:

const ami = new Manager(5038, "localhost", "admin", "secret", true);

// Enable auto-reconnection
ami.keepConnected();

ami.on("connect", () => {
  console.log("Connected to AMI");
});

ami.on("close", () => {
  console.log("Connection lost, will attempt to reconnect...");
});
