Unable to record active call

[Chris Grimmett]

I'm using node and the plivo-node module. What I'm trying to do is call a plivo number, it plays a message then starts recording.

The problem I'm having is that plivo can't seem to find the active call uuid when I do api.record(...)

Here's my code (record is not in the right order. right now I'm just trying to get a proof of concept):

var express = require('express');
var nconf = require('nconf');
var plivo = require('plivo-node');
var bodyParser = require('body-parser');
var urlencodedParser = bodyParser.urlencoded({
    extended: true
});
var app = express();

nconf.file('./config.json');

var api = plivo.RestAPI({
    authId: nconf.get('PLIVO_ID'),
    authToken: nconf.get('PLIVO_TOKEN')
});



app.post('/call/answer', urlencodedParser, function(req, res) {

    var uuid = req.body.CallUUID;
    var recordAttributes = {
        call_uuid: uuid,
        time_limit: 30,
        file_format: "wav"
    };
    var r = plivo.Response();


    console.log('got call', uuid);

    api.record(recordAttributes, function(status, response) {
        console.log('got response:', response);

        if (status >= 400) {
            console.log('could not record', status);
            r.addSpeak('could not record');
            res.set({
                'Content-Type': 'text/xml'
            });
            return res.end(r.toXML());
        }
        else {
            r.addPlay('https://s3.amazonaws.com/plivocloud/Trumpet.mp3');
            res.set({
                'Content-Type': 'text/xml'
            });
            return res.end(r.toXML());
        }
    });
});


app.listen(process.env.PORT);

Here's what plivo returns as the response to api.record():

got response: { api_id: '847e1bf4-0e11-11e5-b483-22000afb8d0a',
  error: 'call not found' }

Using the plivocloud web debug interface, it looks to me like it received good data (I've masked out my auth id):

             Message : response error
             Status : 404

             URI:  /v1/Account/xxxxxxxxxxxx/Call/83a03dc0-0e11-11e5-b86c-6f59143e3963/Record/
             Method:  POST
           
             Params : {
                  time_limit : 30
                  file_format : wav
                }
           
             Response : {
                  api_id : 847e1bf4-0e11-11e5-b483-22000afb8d0a
                  error : call not found
                }
     

...yet It wasn't able to find the call and record it.

Does anything look really wrong in my code?

Hello Chris,

Assuming that "/call/answer" is your answer_URL for the call, you are trying to start the record api before returning a valid XML (Play music). Instead of using Record API to record the call, you could use Record XML. The XML returned by the answer URL would look something like this:

<Response> <Play>https://s3.amazonaws.com/plivocloud/Trumpet.mp3</Play> <Record action="http://foo.com/get_recording/" maxLength="30" finishOnKey="*" /> </Response>
