The Twilio web sockets are used by our various SDKs but aren't publicly documented as they aren't for public use. They don't use your SIP credentials to connect, but are used for real time data in SDKs like Twilio Chat.

How can an Application Server send a downlink message to a LoRaWAN end device connected to Actility ThingPark Community platform?
ThingPark Community Platform offers a REST API to allow Application Servers sending a downlink message to an end-device. Every http request sent to that API need to be validated by a one-time token so that ThingPark can verify the integrity of the request.
The interface between ThingPark Enterprise Network Server and an external Application Server is described in the TPE LRC AS tunnel interface development guide.
For a quick test please check our simple javascript example.
Don't forget to update the constants at the beginning of the script.
The AS_KEY is the Tunnel Interface Authentication Key that you set on the
CREATE HTTP APPLICATION form.
The AS_ID is the Application ID that you can see once you have creeted the application.
If you prefer testing with curl see our curl test shell script.
Please note that this script does not calculate the one-time token. You need to calculate it yourself according to the Tunnel interface development guide or by studying the former javascript code.
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.
We have used Erlang/Cowboy to develop a simple chatting service based on WebSockets. Right now, We are using localhost:8080 to connect server.
I want to do user authentication, that will be done based on the URL parameter, and it will return user id or none for the connection.
How to do that?
Before the websocket exchange, you can ask a token to your application and use it with your websocket client.
Working on a data collection application using mobile sms.
when a customer send a sms lets say
SMS content
Demo CET 100-50030-2320-1000
when the sms reach the mobile serive provider it send a GET request on my server
http://domainname.com/demo.aspx?mno=9828958745&sms=CET+100-50030-2320-1000
Now the problem is some hackers are sending GET request from there PC browser and all the data is getting missed and server is getting overload
I want to know which request is from a computer(mobile server) and which are from browser.
thanks in advance

Check if the request for a page is coming from a server not a browser.
If your service is not meant to be accessible publicly you have to protect it instead of publishing it on the internet. Some wasy to protect it:
HTTP Authentication
IP restrictions in firewall.
IP restrictions in the service.
Virtual Private Network.
