ami-io - node.js/io.js client for Asterisk AMI.

This is a AMI client. List of available commands is below.

Install with:

npm install ami-io

Usage

Simple example:

    var AmiIo = require("ami-io"),
        SilentLogger = new AmiIo.SilentLogger(), //use SilentLogger if you just want remove logs
        amiio = AmiIo.createClient(),
        amiio2 = new AmiIo.Client({ logger: SilentLogger });

    //Both of this are similar

    amiio.on('incorrectServer', function () {
        amiio.logger.error("Invalid AMI welcome message. Are you sure if this is AMI?");
        process.exit();
    });
    amiio.on('connectionRefused', function(){
        amiio.logger.error("Connection refused.");
        process.exit();
    });
    amiio.on('incorrectLogin', function () {
        amiio.logger.error("Incorrect login or password.");
        process.exit();
    });
    amiio.on('event', function(event){
        amiio.logger.info('event:', event);
    });
    amiio.connect();
    amiio.on('connected', function(){
        setTimeout(function(){
            amiio.disconnect();
            amiio.on('disconnected', process.exit());
        },30000);
    });

Used events you can see below.

Standalone run

You can use node index.js user password [host[:port]] [-h host] [-p port] to test lib and watch events on screen. Also, if you use -f filePath parameter on run - before close node, it will try to write array of events to file.

API

Connection Events

client will emit some events about the state of the connection to the AMI.

"connectionRefused"

client will emit connectionRefused if server refused connection.

"incorrectServer"

client will emit incorrectServer if server, you try connect is not an AMI.

"incorrectLogin"

client will emit incorrectLogin if login or password aren't valid.

"connected"

client will emit connect after connect to AMI and success authorize.

"disconnected"

client will emit disconnect when connection close.

AMI Events

"event"

client will emit event when has new event object. All of them should find at https://wiki.asterisk.org/wiki/display/AST/Asterisk+11+AMI+Events.

"responseEvent"

client will emit responseEvent when some response has event as part of itself.

"rawEvent"

client will emit rawEvent when has new event object or a part of response object. Note that use event and rawEvent at the same time is not a good idea.

"rawEvent."+eventName

client will emit rawEvent.+eventName when has new event object or a part of response object. You can find event names at https://wiki.asterisk.org/wiki/display/AST/Asterisk+11+AMI+Events

Methods

amiio.createClient()

• amiio.createClient() = amiio.createClient({port:5038, host:'127.0.0.1', login:'admin', password:'admin', encoding: 'ascii'})

If some of object key are undefined - will use default value.

• host: which host amiio should use. Defaults to 127.0.0.1.
• port: which port amiio should use. Defaults to 5038.
• login: Default to admin.
• password: Default to admin.
• encoding: which encoding should amiio use to transfer data. Defaults to ascii. Be careful with changing encoding to any other value manually, cause in order to AMI's protocol spec, AMI use ASCII.

client.connect([shouldReconnect[, reconnectTimeout]])

When connecting to AMI servers you can use: client.connect(true) to create connection with auto-reconnect. Auto-reconnect works only if auth was success. If you use client.disconnect() connection will close and shouldn't be any reconnect. If use client.connect() reconnect will not work.

Default reconnect timeout is 5000ms.

Also you may want to set timeout of reconnecting. Then use client.connect(true, timeoutInMs). You don't need to set up timeout for every time you connect (in one client object). After client.disconnect() timeout will not be set to default, so you can use client.connect(true) to connect again with similar timeout.

client.disconnect()

Forcibly close the connection to the AMI server. Also stop reconnecting.

    var amiio = require("ami-io"),
        client = amiio.createClient();

    client.connect();
    //Some code here
    client.disconnect();

client.unref()

Call unref() on the underlying socket connection to the AMI server, allowing the program to exit once no more commands are pending.

var AmiIo = require("ami-io");
var client = AmiIo.createClient();

/*
    Calling unref() will allow this program to exit immediately after the get command finishes.
    Otherwise the client would hang as long as the client-server connection is alive.
*/
client.unref();
//will close process if only AmiIo is in it.
client.connect();

client.ref()

Call ref() will cancel unref() effect.

client.useLogger

Use client.useLogger(LoggerObject) if you want to use some another logger. By default use console and ignore any logging levels.

var AmiIo = require("ami-io");
var client = AmiIo.createClient();
var client.useLogger(logger);

logger should has trace,debug,info,warn,error,fatal methods. Of course you can emulate them if some lib has not it.

Extras

Some other things you might like to know about.

client.connected

true if client is connected of false if it is not.

client.reconnectionTimeout

Timeout for reconnect. If you didn't want reconnect ever, client.reconnectionTimeout == undefined.

client.shouldReconnect

true if will be reconnect, or false if will not.

Description of all commands and variables they need, you can find at https://wiki.asterisk.org/wiki/display/AST/Asterisk+11+AMI+Actions All values, needed in commands, should passed like this:

    var action = new amiio.Action.QueueSummary();
    action.queue = "some queue's name";
    amiioClient.send(action, function(err, data){
        if (err){
            //in current time - may be without error. need test
            //err === null if ami response match(/success/i), else response will pass as error
        }
    });

Custom Action

If there is not action you need inside available list, you may build action manual and set all variables and fields by yourself. For example:

var action = new amiio.Action.Action('MuteAudio');

Action Variables

If you need send some variables to AMI, use action.variables object like this:

    var action = new amiio.Action.SomeAction();
    action.variables.VariableA = 1;
    action.variables.VariableB = 2;
    action.variables.VariableC = 3;

Or you can do it like this:

    var action = new amiio.Action.SomeAction();
    action.variables = {
      VariableA: 1,
      VariableB: 2,
      VariableC: 3
    };

Be sure, that you don't use the same names for different values.

Action.Originate

Now, you can send OriginateAction with response like OriginateResponse event. See https://wiki.asterisk.org/wiki/display/AST/Asterisk+13+ManagerEvent_OriginateResponse for description.

    var action = new amiio.Action.Originate();
    action.Channel = 'sip/123';
    action.Context = 'default';
    action.Exten = '456';
    action.Priority = 1;
    action.Async = true;
    action.WaitEvent = true;
    
    amiioClient.send(action, function(err, data){
        if (err){
            //err will be event like OriginateResponse if (#response !== 'Success')
        }
        else {
            //data is event like OriginateResponse if (#response === 'Success')
        }
    });

SilentLogger

If you want remove logs, you may use AmiIo.SilentLogger's instance as logger. Just pass it as argument to AmiIo constructor.
