Audio and video calls are work fine When mobile phones are in the same network,
but when mobile phones are in different network audio and video calls are not work,
we implement our own server using http://help.conversations.im/ this reference.
we can't find solution.
What is the solution to this?
You need a secundary server to make these calls, some servers have some pluggins for example openfire has one called PionTURN as a plug. but any TURN server will do it. i recommend "coTURN" then just install discovery pluggin in your server and configure it to point it to your TURN server.

I am building a free voice call application on Android. I used OpenSIPs open source to make a SIP server and successfully make a call to another phone in WIFI network. However, I couldn't make a call when the phone uses cellular network like 3G/4G. I found out that I should make a STUN and TURN server to find exact SIP address.
Someone told me that it is hard to find SIP address if the user uses 3G or 4G network. So, he said I should use SBC to redirect voice data if I want to make good connections. He said I should make redirect servers to have good quality of service.
Is it possible to make a good voice call service with OpenSIPs server? If it is true, is there voice call services who used OpenSIPs open source? I've searched all documents, but couldn't find the answer.
Thank you.
I decided to make a SIP server using FreeSwitch Open Source. It was much better than OpenSIPs. I didn't have worry about NAT problem on FreeSwitch. It is also very easy to install a SIP server on Linux. Check out the website. http://freeswitch.org/
I am keen to get some apps built that can communicate with other devices/ web etc. i have played around with FTP and can get so far. But what is the best way to do this? We don't have any Servers with databases etc, but do have a site that we are currently uploading and downloading files to.
can anyone suggest a good/ better way to get the device to send/ receive files?
thanks

If it's HTTP communication you're wanting to do, the simplest and most powerful tool is ASIHTTPRequest.
HTTP is the protocol your web browser uses to talk to web servers. If you have a site you're storing and downloading files at, it's almost certainly HTTP you're talking to it.
For iOS device to device communication one can use Bump API.
EDIT: I don't know of a generic framework for device <-> server communications, but having built applications that use web services of other providers like Yelp, Yahoo, Google Maps, I would say the way to go for this is to have REST based web services which exchange data in JSON format.
I want to check the network requests an app is making from my iPhone. It's on the same WiFi network as my computer (or if it makes things easier, I can set it up to use an ad-hoc network). I don't want to see every packet, just the URLs which my iPhone is requesting. I don't care about the returned data all that much.
A simple solution would be much appreciated.
If you want to intercept the phone itself you'll need to point it at an http proxy you set up on a computer and watch the requests come through. Something like http://www.charlesproxy.com/ or there are most likely many free proxies.
Connect your computer to the rest
of your local network via Ethernet.
Turn on Internet Sharing from the
Sharing System Preference to share
your Ethernet connection via
AirPort.
Set your iPhone to
connect to the computer as its base
station.
Use Wireshark to
capture and analyze the packets.
I found a really nice repo on github named Wormholy https://github.com/pmusolino/Wormholy it will show every network request on your iphone, you only add it to your pod file and then on your app, you shake your phone and you will see all requests.
Easy to install
Transparent on your app usage
Overview and details of your request
Like so

How do apps like Apple's "Remote" app control mac applications and send data?
is this via php with exec() commands or some other method? and how would I do it in c?
Also, how fast is this rate of transfer (can I use it to send real-time data like streaming video or audio?)
thanks to anyone who cares to enlighten me on this issue :-)
Apps generally communicate using a TCP/IP based protocol and the wireless LAN connection (the iPhone also has Bluetooth). In the case of the Remote app the communication is via with the Digital Audio Control Protocol. iTunes implements DACP so the Remote app can control it. Other common protocols are HTTP and FTP. There are classes in the iPhone SDK to connect to noth HTTP and FTP servers. There is also the Cocoa HTTP Server project which allows the iPhone to act as a HTTP server.
iPhone apps can also use Bonjour/mDNS/zeroconfig (they're different names for the same technology) so that the user doesn't have to be concerned with configuring IP address'.
The data transfer rate of the wireless connection is faster enough to stream video.
many of these remote applications work by installing client software on the computer and establishing a network connection. In the case of Apple's remote software, the client software is built into the networking capabilities of iTunes. You must authenticate using your iTunes sign in and be on local wifi.
The third party app "intelliremote" works very similarly only has it's own client software to install and can work across a WAN with proper port forwarding enabled on your network.
I haven't encountered any realtime streaming options as most of these utilities are designed to pass control messages and meta-info on media files.
I have to write an iphone application that controls a device. This device exposes a telnet based interface. The application should ideally have user access control and customizability for each user.
I was thinking of writing C++ classes that would communicate with the device using sockets. This functionality can then be exposed through web-services that can be called by the iphone application.
However as i looked into it deeper, the api allows you to register for events using telnet and then you can receive notification when those events occur. That kinda put a spanner in the works for me. I for one dont know a "push" scenario can work with webservices.
First off i have never programmed for the iphone so far. So i am not really sure what can be done. So i was thinking if instead of having a webserver to go through, why not have the application independently running on the iphone, directly communicating with the device using sockets. The question though is, is that possible and second i am thinking it would raise a security aspect. First we could control security as everything was going through our central server. Is there a way to handle security (in the sense who has access to the device) without having a central server.
I am sorry that this seems like an unorganized post, but iam trying to brainstorm here.
Looking forward to hear your opinions.
Look up the NSPort and NSStream classes.
I'm looking to do this same thing. Have a program running on one computer and want to send/receive telnet commands from iOS. Built one for Android using the Commons library- which has a telnet client API, but don't know the best way to do it in Objective-C (without writing a telnet client library).
As a start, however, I found the OFC library on Google Code. Looks like something of a Commons-like feel, and there seems to be a telnet client. You might take a look at that.
