    $ npm i asterisk-ami-client

    NodeJS versions

    support >=4.0.0


    It is only some usage cases.

    Example 1:

    Listening all events on instance of client;

    const AmiClient = require('asterisk-ami-client');
    let client = new AmiClient();
    client.connect('user', 'secret', {host: 'localhost', port: 5038})
     .then(amiConnection => {
             .on('connect', () => console.log('connect'))
             .on('event', event => console.log(event))
             .on('data', chunk => console.log(chunk))
             .on('response', response => console.log(response))
             .on('disconnect', () => console.log('disconnect'))
             .on('reconnection', () => console.log('reconnection'))
             .on('internalError', error => console.log(error))
                 Action: 'Ping'
         setTimeout(() => {
         }, 5000);
     .catch(error => console.log(error));

    Example 2:

    Receive Asterisk's AMI responses with promise-chunk.

    const AmiClient = require('asterisk-ami-client');
    let client = new AmiClient({reconnect: true});
    client.connect('username', 'secret', {host: '', port: 5038})
        .then(() => { // any action after connection
            return client.action({Action: 'Ping'}, true);
        .then(response1 => { // response of first action
        .then(() => { // any second action
            return client.action({Action: 'Ping'}, true);
        .then(response2 => { // response of second action
        .catch(error => error)
        .then(error => {
            client.disconnect(); // disconnect
            if(error instanceof Error){ throw error; }

    or with co-library for sync-style of code

    Example 3:

    Receive Asterisk's AMI responses with co.

    const AmiClient = require('asterisk-ami-client');
    const co = require('co');
    let client = new AmiClient({reconnect: true});
    co(function* (){
        yield client.connect('username', 'secret', {host: '', port: 5038});
        let response1 = yield client.action({Action: 'Ping'}, true);
        let response2 = yield client.action({Action: 'Ping'}, true);
    }).catch(error => console.log(error));

    Example 4:

    Listening event and response events on instance of client.

    const AmiClient = require('asterisk-ami-client');
    let client = new AmiClient({
        reconnect: true,
        keepAlive: true
    client.connect('user', 'secret', {host: 'localhost', port: 5038})
        .then(() => {
                .on('event', event => console.log(event))
                .on('response', response => {
                .on('internalError', error => console.log(error));
            client.action({Action: 'Ping'});
        .catch(error => console.log(error));

    Example 5:

    Emit events by names and emit of response by resp_${ActionID} (if ActionID is set in action's data package).

    const AmiClient = require('asterisk-ami-client');
    let client = new AmiClient({
        reconnect: true,
        keepAlive: true,
        emitEventsByTypes: true,
        emitResponsesById: true
    client.connect('user', 'secret', {host: 'localhost', port: 5038})
        .then(() => {
                .on('Dial', event => console.log(event))
                .on('Hangup', event => console.log(event))
                .on('Hold', event => console.log(event))
                .on('Bridge', event => console.log(event))
                .on('resp_123', response => {
                .on('internalError', error => console.log(error));
                Action: 'Ping',
                ActionID: 123
        .catch(error => console.log(error));
