I am using twiml bin attached to one of my twilio numbers.
When a person calls that number it should be able to dial multiple numbers. I want to stream the call only when the call has been picked up. There can be multiple ongoing streams associated with a twilio number.
<Response>
<Start>
<Stream track="both_tracks" url="wss://XXXX.ngrok.io /twilio-stream">
</Stream>
</Start>
<Dial answerOnBridge="true" >
<Number>+91XXXXXXXXX</Number>
<Number>+91XXXXXXXXX</Number>
</Dial>
</Response>
The above twiml starts the stream as soon as the number is dialed. I want it to start the stream only when the call is received at the other end.
Unfortunately, there isn't a way to do this today, without REST API endpoint control.
You can use the REST API Calls resource to initiate calls intead. The approach you are taking doesn't work very well when the dialed parties are mobile end-points in poor coverage areas and/or devices with voicemail enabled.

I am not able to do simple 2 way audio call between 2 numbers using twilio.
I have attached my python (Django) code. when I run the code, call Get connected and but after accepting call it get's disconnected immediately. also, I am not able listen to anything on Laptop.
I have joined the code and twiml from twilio.
def call_m(request):
account_sid = os.environ['TWILIO_ACCOUNT_SID']
auth_token = os.environ['TWILIO_AUTH_TOKEN']
client = Client(account_sid, auth_token)
call = client.calls.create(
url='twiml_url',
to='+91985XXXXXXX',
from_='+132YYYYyYYY',
)
print("sid ",call.sid)
return render(request, 'calls/incall.html')
Here's my twiml.
<?xml version="1.0" encoding="UTF-8"?>
<Response>
</Response>
if i changed My twiml to this
<Response>
<Dial>+9198xxxxxxxx</Dial>
</Response>
then after accepting call from "To" number, It say's number is busy please call later.
I think you may have some misconceptions about how Twilio works when making calls.
When you generate a call with Twilio using the REST API that creates a call leg between the to number and Twilio (not between your laptop and the phone).
When that call is answered on the end of the to number, Twilio then makes an HTTP request to the url that you passed to the API. That URL should respond with TwiML to tell Twilio what to do with the call next.
Now, when your application responded with an empty TwiML response (<Response></Response>) that tells Twilio that there is nothing left to do in this call, so Twilio hangs up.
When your application responded with a <Dial>, like this:
<Response>
<Dial>+9198xxxxxxxx</Dial>
</Response>
my guess is that the number in the dial was the same number that you used in the to parameter to make the call. In this case, Twilio placed a call to your number in response to the REST API request and then placed another call to your number as directed by the TwiML <Dial> and that second call found that your number was busy because you are already on the line with Twilio.
If you used a different number in the <Dial> then Twilio would place a call to that number and when they answered the phone you would be connected to them.
If you want to connect two callers with their own phones, then using <Dial> like this is the way forward.
If you want to place a call from your laptop to another device, then you will need a bit more than just the REST API. In this instance you need to build an application using the Twilio Voice SDK which allows you to make calls from a web browser or iOS or Android application. If this is of interest to you then I recommend you check out the getting started guide for the JavaScript voice SDK.
The call needs TWiML to stay active, so that explains why it ends the call when you are returning an empty TwiML reponse. You must keep feeding it TwiML to keep the call up.
Specific to calling the number, there could be an issue dialing that number that Twilio support could investigate, if geographic permissions allow international calls to that destination.
I have a task with this description:
Implement the call button:
When call icon is clicked, first Twilio calls the phone number #1 (Admin)
Once admin picked up the phone, the number #2 (provider) is called.
Both connected.
At this moment I figured out how to call through browser to phone numbers (like Admin can call to the provider in browser).
But I can't find any information, how to connect people through Twilio accordingly the task.
Is there any way to implement this solution?
I do not completely understand if you want to click a phone number on the website or if you want to completely connect two phone numbers automatically.
Scenario 1: User calls a number of your Twilio account
You setup a callback URL for that number and setup a web endpoint which generates a response similar to the following (XML, TwiML):
<?xml version="1.0" encoding="UTF-8"?>
<Response>
<Dial callerId="${callerId}">${targetNumber}</Dial>
</Response>
In my example I use TypeScript/JavaScript templating to replace the callerId and targetNumber variables according to our systems logic.
Secenario 2: You want to connect two phone numbers via Twilio
In this scenario your software first makes sure that Twilio calls your Admin. This can be done via a REST call or Twilio's API. There are so many options depending on which programming language you use and if you want to use a library from Twilio. But the basic idea is documented here:
https://www.twilio.com/docs/voice/make-calls
And you would always end up making a REST call against /2010-04-01/Accounts/{AccountSid}/Calls to initiate the call.
In the request you again specify a URL where Twilio then can read back XML / TwiML to understand what it should do with the call one it is connected. And again here you can use almost the same TwiML as above:
<?xml version="1.0" encoding="UTF-8"?>
<Response>
<Say>Just a second you are going to be connected to your provider.</Say>
<Dial callerId="${callerId}">${targetNumber}</Dial>
</Response>
In the above example I also added a <Say> statement such that the administrator knows, that they are going to be connected and need to be patient until the call is finally connected.
Important Notes:
In our application scenarios we are attempting to hide the phone numbers of the connected parties. The purpose is that the caller which dials into our system should have the opportunity to remain completely anonymous if desired. So we specify with callerId which caller id we want to send with outbound phone call. Bear in mind that this must be a phone number which you do own (is a number rented via Twilio or is a phone number you registered with Twilio).
I want to use the Whisper in Twilio Studio,
is this possible??
Now I using only Twilio Studio and TwiML Bin
my goal is...
User calls to my Twilio number
Connect call to the support team phone.
After starting the calls between the User(client) & the support team, I want to [Say] a message to the support team then start the calls.
How can I do this??

Currently you cannot do a whisper with Studio. You could achieve this flow with just TwiML Bins though.
You would need two bins. One to read the message that you want in the whisper and the other two forward the call and point to the whisper.
So, the whisper bin would include TwiML using either <Say> or <Play> for the message, like this:
<Response>
<Say voice="alice">You are getting a call on the support line, the next voice you will hear is the customer.</Say>
</Response>
Then, the bin that responds to the incoming call needs to use <Dial> with a <Number>. The <Number> url attribute should point at the TwiML above for the whisper. Like:
<Response>
<Dial>
<Number url="TWIML_BIN_URL">+123456789</Number>
</Dial>
</Response>
We're trying to use Twilio to create an automated test framework for those IVRs.
We do an outbound call from Twilio to the IVR, use the verb Say/Play to interact with the IVR and we're using Record to capture what the IVR is saying, latter we transcribe it and make the assertions.
When I ask Twilio to call a phone number and I pretend to be the IVR, everything works perfectly. But when I ask Twilio to call the real IVR, apparently the Record verb can't recognize the pauses, when the IVR stops talking and is waiting for some input.
We tried tweak the timeout attribute but no luck, it records everything and only when the IVR ends the call, Twilio give me the callback with the entire recording. We want each interaction with the IVR in a separate audio, the way we have when I'm pretending.
Here is an example of the TwiML with the Record verb:
<?xml version="1.0" encoding="UTF-8"?>
<Response>
<Record action="http://foo/nextStep"
method="POST"
playBeep="false"
recordingStatusCallback="http://foo/recordStatus"
timeout="2"
transcribe="false"
trim="do-not-trim" />
</Response>

Rather than using <Record> for this, I would recommend using <Gather input="speech">. The intention of speech input with <Gather> is to react to input to build a voice enabled IVR, but I can only imagine that it will work better in this testing scenario too. It will live transcribe the results for you in place of returning the recordings for you.
Let me know if that helps.
I am new to twilio. I am trying to setup a phone number that rings multiple destinations.
I followed this blog and set up a twiML script like so.
<?xml version="1.0" encoding="UTF-8"?>
<Response>
<Dial>
<Number>+1-777-777-7777</Number>
<Sip>sip:1777xxxxxxxxxx#in.callcentric.com;region=us2</Sip>
<Sip>sip:1777xxxxxxxxxx#in.callcentric.com;region=us2</Sip>
</Dial>
</Response>
However as reported by other users in the comments this does not seem to work for scenarios where the destinations are a mix of sip and numbers. In my case only the phone number rings. The sip destinations don't receive the call at all.
Is there a way to make this work? either with bins or the new twilio functions?
Twilio developer evangelist here.
It is not possible to use multiple <Sip> nouns in a <Dial>. From the documentation:
Currently, only one <Sip> noun may be specified per <Dial>, and the INVITE message may be sent to only one SIP endpoint. Also, you cannot add any other nouns (eg <Number>, <Client>) in the same <Dial> as the SIP. If you want to use another noun, set up a callback on the <Dial> to use alternate methods.
You could, instead, add the incoming caller to a queue with <Enqueue> and dial each of the numbers/SIP addresses using the REST API. Then, when one connects, connect it to the call in the queue and disconnect the other calls. You'd need to keep a reference to the original call SID so that could connect directly to it and to each of the generated call SIDs so that you can terminate them with the REST API too.
Let me know if that helps at all.
