VOIP using XMPP Framework in iPhone [closed]

Question

I am able to implement Facebook and Gmail chat with the help of XMPP Framework in my iPhone app. Wanted to know if its possible to implement VOIP(SIP) in a similar manner using XMPP.

Answer 1

You can use jingle framework.This is what jingle wiki says: "Jingle is an extension to the Extensible Messaging and Presence Protocol (XMPP) which adds peer-to-peer (P2P) session control (signaling) for multimedia interactions such as in Voice over IP (VoIP) or videoconferencing communications. It was designed by Google and the XMPP Standards Foundation. The multimedia streams are delivered using the Real-time Transport Protocol (RTP). If needed, NAT traversal is assisted using Interactive Connectivity Establishment (ICE)."

The libjingle library, used by Google Talk to implement Jingle, has been released to the public under a BSD license. It implements both the current standard protocol and the older, pre-standard version

Also there is a framework in Google project repository. http://code.google.com/p/libjingle/

Also, one more link related to this: iOS: Open Source VoIP/SIP Objective-C Code

May be this will give you an idea.

Answer 2

Its possible to implement VOIP using XMPP. For ios many are providind SDK's which you can easily implement in your code. Among that one of the best is QuickBlox, which is very useful and easy to implement. Its providing P2P video chat, text chat , group chat and file transfer facilities.

But now WebRTC is gaining much popularity for VOIP purposes.WebRTC (Web Real-Time Communication) is an API definition being drafted by the World Wide Web Consortium (W3C) to enable browser to browser applications for voice calling, video chat and P2P file sharing without plugins.

Open Tok is a rather useful product which can be used for VOIP calling in ios devices. They are also providing a basic IOS sdk for easy implementation.
