Requirements

• nodejs >= 0.7.0 available here
• npm - node package manager ( installed by default with nodejs )
• CALLR npm package available here

---

Installing

1. To get started with the CALLR npm package, first create your project directory then base project files using npm init. npm init initialises the project with a package.json, which contains meta data about your project or app, including modules needed for it to run.

   // create your project
   $ mkdir myproject
   $ cd myproject
   $ npm init
   ...
   About to write to /working/myproject:
   {
       "name": "myproject",
       "version": "1.0.0",
       "description": "",
       "main": "index.js",
       "scripts": {
           "test": "echo \"Error: no test specified\" && exit 1"
       },
       "author": "",
       "license": "ISC"
   }
   Is this ok? (yes)
   

2. Install and add the CALLR SDK to your application dependencies.

   $ npm install --save callr
   myproject@1.0.0 /working/myproject
   `-- callr@1.0.0
   
   npm WARN myproject@1.0.0 No description
   npm WARN myproject@1.0.0 No repository field.
   

3. require the CALLR sdk in your project source to begin using.

   var callr = require('callr');
   var api = new callr.api('login', 'password');   
   
   api.call('system.get_timestamp').success(function(response) {
       // success callback
   }).error(function(error) {
       // error callback
   });

---

Running

Export your CALLR credentials as environment variables:

// bash
$ export CALLR_LOGIN=<your_login>
$ export CALLR_PASS=<your_password>

// windows cmd
c:\> set CALLR_LOGIN=<your_login>
c:\> set CALLR_PASS=<your_password>

Examples

Simple voice campaign

This will guide you through the commands and output needed to create a simple voice campaign, that utilises 2 different sources of media.

1. Upload our pre-recorded mp3 and create our TTS media

   // upload mp3
   $ node media upload samples/sample-recording.mp3 -n 'mp3 recording'
   Import job id: 358c1467123456789123456789ABCDEFG, mp3 recording
   Media uploaded: mp3 recording, id: 1012345
   
   // create tts voice message
   $ node media create-tts -n 'my tts' -t 'Hello, welcome to our simple voice campaign' TTS_EN-GB_SERENA
   media created, id: 1023456
   

2. We can check our media library to make sure the creation was successful.

   // list media library contents
   $ node media list
   ...
   media id: 1012345, name: mp3 recording, content: , voice: NONE, source: API_IMPORT
   media id: 1023456, name: my tts, content: Hello, welcome to our simple voice campaign, voice: TTS_EN-GB_SERENA, source: TTS    
   

3. Next we need to upload our addressbook, this is done with the address.js script:

   // upload addressbook
   $ node address upload -c FR -n "my addressbook" -p 2 samples/sample-addressbook.csv
   Import job id: 358c146764abcdefghijklmno123, my addressbook
   Addressbook LH9Q92DC - my addressbook successfully uploaded.
   

   • -c determines the country code for the phonenumbers listed in the addressbook
   • -p is the zero based index of the phonenumbers column in the csv/excel document.
     ( see node address upload -h for more information )

4. We can list our addressbooks to confirm the upload, or view the ids of already imported addressbooks:

   // list addressbooks
   $ node address list
   id: LH9QABCD - name: my addressbook, items_count: 5, imported: 2016-01-01 12:00:00
   Total of 1 addressbooks found 
   

5. Next we create our simple voice campaign using the campaign script, using the addressbook id, and media ids.

   // create voice campaign
   $ node campaign create -t 'my simple voice campaign' -a LH9Q92DC -m 1012345,1023456 VOICE_SIMPLE
   Campaign created ID: QRTCA1B2 
   

   • -t is our name for the campaign
   • -a determines which addressbook to use for the campaign
   • -m denotes a comma separated list of media files to use for said campaign
   • VOICE_SIMPLE denotes the type of campaign we are creating ( see node campaign create -h for more information )

6. With our returned campaign id, we can perform different operations, start / stop / pause, retrieve the config or view the status. ( see node campaign -h for more information )

   // show campaign status
   $ node campaign status QRTCBFTO
   {
   "run_id": 1,
   "state": "CREATED",
   "finished_cause": "NONE",
   "finished_cause_data": null,
   "percent": 0,
   "items_done": 0,
   "items_total": 5,
   "items_total_t": 5,
   "counters": {
       "broadcast": {
           "completed": 0,
           "history": {}
       },
       "cost": "0.00",
       "call_status": {
           "ANSWERED/COMPLETE": 0,
           "ANSWERED/INCOMPLETE": 0,
           "ABSENT/NO_ANSWER": 0,
           "ABSENT/BUSY": 0,
           "ABSENT/VOICEMAIL_DETECTED": 0,
           "ERROR/UNALLOCATED_NUMBER": 0,
           "ERROR/REJECTED": 0,
           "ERROR/BLACKLISTED": 0,
           "ERROR/OTHER": 0
   ...    
   "scheduled": false,
   "started_at": "0000-00-00 00:00:00",
   "ended_at": "0000-00-00 00:00:00",
   "reports": [],
   "state_history": []
   }
   

Send sms

To send a sms, use the send-sms.js script

$ node send-sms.js -t +33123456789 -m "Hello, from test sms!"
sms sent id: 6CQLABCD

Click2Call full web demo

Please see the README here for more information on running the full Click2Call web demo application.

Create ClickToCall

To create a simple click to call application, use click2call.js, here we will create a click to call application with a tts media that will be played to person A before they are connected to person B.

For more information on the Click to Call api, see the documentation here and related objects here.

1. Create our tts media file, with a simple greeting. ( see Sample scripts for more information on using the media script )

   $ node media create-tts -t 'Hello, connecting you to home base, please hold' -n 'my greeting' TTS_EN-GB_SERENA
   media created, id: 1051111
   

2. Create the click to call application, passing the media to be played to callee A before connecting them to callee B

   $ node click2call.js create -m 1051111 'my click2call application'
   Click2Call app created, id: N9BUABCD  name: my click2call application
   

3. Start the click to call application, passing the 2 telephones to be connected

   $ node click2call.js start -a +33123456789 -b +33123456987 N9BUABCD
   Click2Call application started, call id: PHABCD1U
   

4. A call will be first placed to person A, and the media file passed to Click to call creation will be played before being connected with person B.
