In Twilio Rest API for each call there is a response which uniquely identify calls
Twilio-Request-Id: RQ5cedae4e7e7e4e70937a8198f5d2d1c0
Twilio-Request-Duration: 0.103
I want use Twilio Elastic SIP Trunking Call. So messages will be in raw SIP formats.
I wonder if Twilio provides this unique response Id-s(which you can use to identify your call details uniquely by) as custom SIP Headers extensions such as
X-Twilio-Request-Id = ...
X-Twilio-Request-Duration = ...
And what other custom SIP extension headers provided by Twilio about calls which are done via Elastic SIP Trunking?
It seems that Twilio send a unique Id in SIP OK Response
X-Twilio-CallSid: CA70554....

If my code tries to make a call to a SIP endpoint, and that endpoint is no longer registered, the call fails with error 32009 - Dialing SIP Endpoint failure - User not registered.
From what I've read, the only way to prevent this from happening is from manually searching for the endpoint via https://www.twilio.com/console/voice/sip/endpoints/SDXXXXXXX.
Is there any way to verify a SIP Endpoint is registered with the Twilio API prior to initiating the call?
There is not. Use the DialCallStatus to take an alternate action if the device is not registered.
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 using Twilio for my cloud communication platform. A client of ours wants to SIP over to us, with headers, so we can continue the call on our end using Twiml.
I have tried setting up a SIP Domain and it works if I use a soft phone for an end point, but this isn't what I am trying to accomplish. I have also tried setting up a SIP Elastic Trunk and have that trunk connect to our SIP domain which in return call the Voice URL on the SIP domain.
I currently have setup a simple application to test this process. I have a Twilio number that calls a webhook, in the webhook (my app) I call the sip to the Twilio SIP trunk, but it fails. I am expecting to call the SIP domain and the Voice URL. I keep getting the error that the You tried to Dial a SIP Endpoint that is not currently registered with the corresponding SIP Domain. Please check your TwiML or REST API. (reference: TWilio Error Documentation.
Can anyone help me with this, please? I am currently using Twiml with PHP.

I am also following this documentation to a tee. I have a SIP Domain setup in my Twilio account, but it is requiring a registered user at an endpoint. In this documentation, it says when a sip call comes into the sip domain it will call the webhook, which it is not doing. Twilio SIP Domains

I believe you're right to be confused about the SIP domain documentation. But the error message clears it up when it says:
Make sure the username matches a username in the Credential List used to authenticate the SIP Endpoint with the SIP Domain.
So your username does need to be an existing one, the SIP domain is not acting as a wildcard catch all for SIP addresses.
I will work to make sure the documentation is clearer.
Given that you are already receiving a webhook from an incoming call, why are you trying to get a second webhook from the SIP request? Could you not use the first webhook to direct the call the way you need?
In general, if you try to call a SIP endpoint via a SIP server/proxy, that SIP server/proxy needs to know how to reach that endpoint (routing). From the error text I derive that that isn't possible at the moment. Also, sometimes SIP servers only allow outbound calls from registered endpoints.
There are a number of things you can do:
Bypass the SIP server and call the endpoint directly (probably not what you want)
Configure a static path in the SIP server to the endpoint
Have the endpoint(s) register at the SIP server, so the SIP server knows who calls and how to reach the target.
Have you tried the possible solutions in the Error documentation?
Make sure the username (in the Request-URI) matches a username in the Credential List used to authenticate the SIP Endpoint with the SIP Domain
Prior to dialing, you can verify that your SIP Endpoint has successfully registered in the Console "Registered SIP Endpoints" tab found on the SIP Domains page.
I am using freepbx to connect to twilio elastic sip trunk. Which domain for incoming and outgoing URL to be used and how to authenticate it ?
Can I use softphone like eyebeam or x-lite to make call s ? What would be codec value ?
I am using Twilio Voice API to make calls. The flow is that a user initiates an action on my site, we then send a request to Twilio API via the twilio object in the ruby gem. This object contains the
'from' number , 'to' number , 'url'
The 'url' is my API end point, which looks something like this
.../api/v1/users/here
From here, I route the request to one of my controllers' actions to serve up a twiml to play.
My question is: How can I ensure that ONLY TWILIO is able to ping this api endpoint?
a) Is there some kind of identifier in Twilio's request that I can use to validate source?
b) I am using Grape gem to set up the api endpoint. Can I do something with the grape gem for this purpose?
Twilio evangelist here.
Twilio has a special header we send called X-Twilio-Signature that allows you to validate that the webhook request is only coming from Twilio.
The Ruby helper library includes a piece of middleware that you can plug in to check for this header and perform the validation. Check out this blog post for more info:

Hope that helps
A simple way to do this is with an API token. Pick a nice, random string and set up your Twilio URL to include ?token=abcd1234, then on your server, verify that the token is present. Anyone else hitting your endpoint won't have it, so you know it must be Twilio.
