I'd like to work on a SIP project for mobile devices. I've seen links to Siphon, Sipdroid and OpenSIPS.
Does OpenSIPS allow for me to make phone calls between two iOS devices in a local network?
In other words, I'm trying to do an app for a VOIP company. I'd like to set up my own SIP server and then use theirs later. Is there any reason that it would not work?
OpenSIPS is a SIP server application that includes a variety of components that are often needed for a SIP infrastructure such as Registrar, Proxy, Presence Agent etc. What OpenSIPS is not is a SIP user agent (or at least not one that's designed to work with a person as the end user). That means it's not built to make or receive calls.
If you are planning on using OpenSIPS as the SIP Proxy on your network combined with a different piece of software, such as Sipdroid, acting as the user agent on your mobile devices then the answer to your question is yes. You will be able to configure OpenSIPS to allow calls between devices on the same local network.

Is there any way to create your own google IOT device based on webhooks and POST-request? Without using firebase, IFTT, node.js
Samples that Google are very poor, they don`t show all steps of creating your own app, they just showing how to deploy "their sample"
I tried to make action with dialogflow & webhook, it was pretty simple. Just processed JSON in POST request to Azure function.
But when I try to create IOT device, its ask me for fulfilment url and it does not even tries to reach that address. I read about action.device.sync, action.device.execute, it just does not communicate with the specified address, giving simulator some voice command doesn`t affect at all. Are there any ways to create IOT device to work with POST-requests & web-hooks?
The answer is it depends.
There are many different ways to do server-device communication: web sockets, local servers, hub/local control, polling, MQTT, and likely many others. All of these solutions have trade-offs, and work in particular circumstances. Depending on exactly what IoT device you want to build, its requirements and technical specs, and what cloud providers you are using, you may identify what works best.
If you run the sample, you'll see it is sending JSON requests to a server and expect JSON responses back. This is must like Dialogflow & a webhook. In this case, the smart home platform communicates solely with the server.
Your server can then communicate with the device in any way that you want. I'm not too familiar with Azure offerings. It might have an MQTT service as well, or some other sort of push notification service you might be able to use.
If you're seeing simulator issues, you may need to make sure your authentication is set up correctly, and you'll need to first complete account linking on your phone before you can use the simulator.
I'm currently researching about how to make an iOS VoIP app and I wondering how user1 of Skype, Viber, Facebook Messengers... can reach to other user in contact list? In my case, the users can request a call to admins. Then admins can call back to them with their IP address they were request to server.
The big problem is if users connected to a Wi-Fi to request a call to server, app will send their ip address to admins. But if they have to connected to another Wi-Fi, their IP address will difference with the older.
I don't know how to check when user's IP was changed. And how to update the IP if it occurs. Does anyone faced this problem and can you guys give me some solution about this problem?
For this you have to configure many things.
Usually Skype, Viber, Facebook Messengers configure things like below.
Ideally there should be target on specific IP or something.
That end point to get connect in video call has to configured and come from server end
https://www.vidyo.com/ is really good platform, though have SDK in C++ so in any technology you can configure it easily
To know online / offline user's, better approach is websocket
list of user will also based on websocket or API response
Good platform for websocket - https://github.com/tidwall/SwiftWebSocket
Pushkit is also required thing, when app is in killed ( Terminated ) state then using pushkit silent notification with local notification you can notify user about incoming call
I have two entities which I would like to be able to start a communication:
Hardware Device Using Atmel ATSAMS70 and WINC1500 Wifi Module
HTML 5 App
The idea to have a HTML 5 app is to be able to communicate easily with most of the commercial devices like: Windows computers, Android Phones, Mac OSX computer and iOS devices. Apart from that, I would avoid working with native code at all.
Currently, they can talk with each other using WebSockets but somehow the IP address of the custom board has to be known from HTML 5 to initiate the communication.
In order to do this, I can think of 3 options:
Using WebRTC I can get the local IP address of the browser and then I could do a scan of the local devices considering a 255.255.255.0 network mask.
Have an external server that the hardware device can send its local address which will be later retrieved by HTML 5.
Using Bonjour or some sort of device discovery service between the board and HTML5.
I could not find a way to achieve #3 but #2 seems feasible to me. #1 is what I am doing now, but WebRTC is currently not supported on iOS.
So, is there any other better possibility to achieve this communication?
You don't mention how the WINC1500 unit is being connected to the network but presumably this is in STA mode (acting as a wifi station rather than becoming a software access point or part of an ad-hoc network) and is being provided with its IP details through an existing access point?
Ordinarily I'd suggest that once connected, the device ought to start indicating its availability on the network via a regular UDP broadcast on a specific port but my (admittedly limited) understanding of WebSockets it is that it creates TCP connections. The only implementation of Bonjour that I've seen uses UDP messaging too, that may be why you've had trouble with your third approach.
Your second approach seems more likely to work well. A server at a known (or discoverable) IP on the local network which allows the Atmel device to register itself (and its IP address) and also allows other applications (your HTML 5 WebSockets applications) to request that connection information to allow them to create the WebSocket TCP connections they need.
I suppose that doesn't really answer your question as to "Is there a better way?", other than to say "Not that I can think of, your second approach looks good to me...". Sorry! Sounds like a very interesting project, overall,
Is there any way to communicate between two devices or application with Browser of other devices without having Server in the middle?
If I explain, actually I want to share data between iPhone application and Browser of Desktop, I tried HTTPServer, & played with WebSocket too, but in these case this server plays an important role in between. So If somehow I exchange data between two peers like IP Address, Port number, Then Is it possible to communicate between those two devices using Wi-fi channel without having Server in Middle?
The Way, Right now I have implemented.
The way, I am looking for.
I recently came across http://www.freedomjs.org/ which is suppose to provide p2p functionality in the browser.
I wish to use a VOIP SIP service for video and audio calls. After researching this I found out that doubang is a flexible framework for voip client.
I want to build an app which requires to connect to a customized SIP server for the communication (registration will be the process where user will be provided with an unique identifier with which user can communicate with others through the sip server). My question is can doubang's idoubs voip client communicate with other users using my sip server or it will use its own resource for that.
I am in need of all features like voice call, video call, Instant Messaging, SMS.
Is there any other framework which satisfies my needs?
You could consider linphone a multi-platform opens-source SIP client that is available on iOS among others.
