I am trying to consume a websocket service in a twilio app voice.
`
How do I capture the response from this websocket and process it within my call?
When I create the call I use
twiml
and the parameters for my decision flow

I have referred to the standard Twilio example to make a call from the browser, I was able to implement calling.
const call = await device.connect({ params });
where params are the body of the post request, But is there any way where we can attach a header to this post request?

Using the SDK to start a call isn't an HTTP request. It results in a webhook request from Twilio to your application, but that is different to the initial request from the SDK. You can use the SDK to pass POST request parameters as you have seen, but you cannot pass headers.
If you are trying to pass an Authorization header, then I assume you are trying to ensure that only requests from Twilio are accepted by your application. There's already a way to do this.
Twilio sends an X-Twilio-Signature header with each webhook request. The signature is made up of the contents of the request signed with your Twilio auth token. You can read how this works in depth here.
Alternatively, you can add username:password# to the start of the webhook URL and Twilio will authenticate via HTTP authentication.
I am using Twilio to make sip outgoing calls. I have created a sip domain, registered credential lists. Then i registered in Zoiper using the sip credentials and made an outbound call. It was working successfully.
Similarly i tried using tryit.jssip.net. But there it was asking for a WebSocket uri. What is that WebSocket uri for twilio ?
Is there something to do more in twilio to register sip endpoint in tryit.jssip.net
Sharing the screenshots here.
This is the jssip configuration. I entered sip uri and password. Websocket url is by default wss://tryit.jssip.net:10443. I didn't change it.
Then it got registered and i tried calling from that number. At that time the call got failed with a message Incompatible UDP

Twilio doesn't publicly support SIP over websockets which JSSIP is asking for here. That is why you can't find the websocket URL to use.
If you are looking to use Twilio from a web browser, I suggest you take a look at Twilio Client.
I am currently working from a Twilio sub account and a TwiML app attempting to start an outbound call from a web based client.
I am using the Twilio. Device in the browser to connect to a landline. I have a public end-point exposed (using ngrok) and the TwiML App is successfully configured to POST the call request to the endpoint. I am responding with <Response><Say>Welcome to this call</Say><Dial>+1XXXXXXXXXX</Dial></Response>. When the client "connects" the system simply speaks the message and the number instead of dialing it and then hangs up. This happens regardless of the Say verb being present.
We do have conference calling working between to phone numbers, but getting this web client to call outbound is giving us a little trouble.
[REQUEST PARAMETERS: {"ApplicationSid":["APxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"],"ApiVersion":["2010-04-01"],"agent":["3xxxxxxxxx"],"Called":[""],"Caller":["client:Anonymous"],"CallStatus":["ringing"],"CallSid":["CAxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"],"To":["8xxxxxxxxx"],"From":["2xxxxxxxxx"],"Direction":["inbound"],"AccountSid":["ACxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"]}]
[REQUEST HEADERS: {content-length=278, x-forwarded-proto=https, host=4dxxxxxxx.ngrok.io, content-type=application/x-www-form-urlencoded; charset=UTF-8, connection=close, x-forwarded-for=xxx.xxx.229.114, cache-control=max-age=259200, x-twilio-signature=lflllCdXo004m0wRzw/efN0IAjg=, user-agent=TwilioProxy/1.1}]
Well, feel a like a newbie, but I had forgot to set the content type to one of the required Content-Type headers, text/xml, text/html, or application/xml. With the header in the response Twilio connects the call as expected.
I'm looking to have the webhook which I pass back TwiML whenever there's a call coming inbound pass me the call's SID so in the future I can modify that active in-bound call. For example, (480)-000-000 is calling my Twilio number which then sets off the webhook to retrieve the TwiML. My server will then also get the SID for that call coming in, and send back TwiML to play lobby music. From then my server will have the SID stored into an array for people in the lobby. And one by one connect them with agents as they become open.

Good news, every webhook for an incoming voice call to your Twilio number includes the CallSid in the request parameters.
The parameters are sent to your URL as URL encoded form data so if you're using a web framework it should be fairly straightforward to read the CallSid from the request.
Let me know if that helps!
I've followed the tutorial here https://www.twilio.com/docs/quickstart/client/javascript which will make an outbound call.
How would I go about collecting the Call SID of the outbound leg? I can get the parent Call SID but not the outbound connection.
I would like this id so I can manipulate the live call.
Using Twilio Client there are two parts ,
(1) Incoming API call into Twilio App
(2) Outbound Dial , as a result of TwiML that does a <Dial> on the number entered on the Twilio Client UI . This is done by the TwiML Application set for your Twilio Client
For getting Child SID , which would be the call sid of the outbound leg , your Voice URL setup for the TwiML Application for your Twilio Client , should capture the call SID after doing the .
