Exchange of messages takes place in universally used languages like English, French, etc. where both the users know how to communicate in a common language. Thus chatting on mobile phones is a luxury when both the parties involved know a common language. Hence we have implemented ALLTALK™ which is a Windows 8 phone based chatting application which makes cross language communication possible using mobile programming and networking technology.This application will enable the communication between two persons irrespective of the language each user wishes to use individually. The various modes of communication available in this messenger are through text and voice. Due to the best processing power provided among the available smartphones and high battery life we choose to work on windows 8 platform. Thus we have successfully eliminated the language barrier and enable ease of communication through this application. Keywords: Cross Language communication, instant messenger, socket connection, translator,Windows phone app.

  • A Survey of Open Source Products for Building a SIP Communication Platform
    Hindawi Publishing Corporation Advances in Multimedia Volume 2011, Article ID 372591, 21 pages doi:10.1155/2011/372591 Research Article A Survey of Open Source Products for Building a SIP Communication Platform Pavel Segec and Tatiana Kovacikova Department of InfoCom Networks, University of Zilina, Univerzitna 8215/1, 010 26 Zilina, Slovakia Correspondence should be addressed to Tatiana Kovacikova, [email protected] Received 29 July 2011; Revised 31 October 2011; Accepted 15 November 2011 Academic Editor: T. Turletti Copyright © 2011 P. Segec and T. Kovacikova. This is an open access article distributed under the Creative Commons Attribution License, which permits unrestricted use, distribution, and reproduction in any medium, provided the original work is properly cited. The Session Initiation Protocol (SIP) is a multimedia signalling protocol that has evolved into a widely adopted communication standard. The integration of SIP into existing IP networks has fostered IP networks becoming a convergence platform for both real- time and non-real-time multimedia communications. This converged platform integrates data, voice, video, presence, messaging, and conference services into a single network that offers new communication experiences for users. The open source community has contributed to SIP adoption through the development of open source software for both SIP clients and servers. In this paper, we provide a survey on open SIP systems that can be built using publically available software. We identify SIP features for service deve- lopment and programming, services and applications of a SIP-converged platform, and the most important technologies support- ing SIP functionalities. We propose an advanced converged IP communication platform that uses SIP for service delivery.

  • Designing a Modern XMPP Service with Ejabberd
    ejabberd architecture and challenges in designing a modern messaging service 17th November 2015 Mickaël Rémond <[email protected]> Introduction ejabberd is scalable and versatile enough to adapt to most of the realtime messaging jobs you will want to handle. For many tasks, like corporate messaging, you can consider ejabberd as a standard package. However, to reach high level of scalability and flexibility, you need to consider ejabberd as an XMPP framework. As such, to build your modern messaging system, you need to: Be familiar with XMPP - Prerequisite. Learn ejabberd architecture Learn ejabberd API Work on solution design. Take control of your messaging platform and design it ! ejabberd: Routing messages in a statefull world ejabberd is a message router. Its role is to support real time messaging feature by moving messages from clients to other clients. In that sense it is stateless. However, to integrate in a statefull world, ejabberd has to support statefull features: Stateless: ejabberd is an XMPP server: Its goal is to route XMPP packets between JID. Statefull: In most case ejabberd depends on data (user base, contact list, …) or produce data (message archive, ...) Goal: deploy an ejabberd that is as stateless as possible, by leveraging backends. What are ejabberd backends ? Backends are pluggable modules you can configure to define where you would like to store part or all of your data. Backends provide the data to the feature modules of ejabberd. They can be read-write or read-only if you do not need some of the ejabberd associated features: For example, if you handle user management elsewhere in your infrastructure, you can use a user back-end that can only authenticate users but not create them.

  • Debian's Role in Establishing an Alternative to Skype
    Debian’s role in establishing an alternative to Skype Motivation, Challenges and Tactics Daniel Pocock [email protected] http://www.OpenTelecoms.org mini-DebConf, Paris, November 2012 Daniel Pocock [email protected] Debian’s role in establishing an alternative to Skype Introduction Motivation – why do we need to do something? What happens if we do nothing? Challenges – why hasn’t it been done already? Tactics – what can we do over the next 12 months? Daniel Pocock [email protected] Debian’s role in establishing an alternative to Skype Motivation Some background Yes, you’ve seen me before – in Managua. Slides and video are available and highly recommended. Is there something new? – yes. Daniel Pocock [email protected] Debian’s role in establishing an alternative to Skype Motivation Why mention Skype? Widely deployed – hundreds of millions of users Interdependency – unlike other types of software, interoperability is a critical factor in the success of real-time communications software Viber – another proprietary solution that has quickly gained traction thanks to ease of use. The free software community missed the boat in the desktop VoIP arena, now the same may be happening for mobile. Daniel Pocock [email protected] Debian’s role in establishing an alternative to Skype Motivation How bad is it? Marketing – Skype allows Microsoft to study your thoughts and emotions in real time. Feedback to advertisers. Privacy – Microsoft has patented a technique for monitoring Skype. Call records, friend lists, etc. Statistical techniques for identifying who is pregnant, who is a homosexual, have all been exposed recently.

  • How to Install and Configure Jabber Server (Ejabberd) on Debian Lenny GNU / Linux
    Walking in Light with Christ - Faith, Computing, Diary Articles & tips and tricks on GNU/Linux, FreeBSD, Windows, mobile phone articles, religious related texts http://www.pc-freak.net/blog How to install and configure Jabber Server (Ejabberd) on Debian Lenny GNU / Linux Author : admin I've recently installed a jabber server on one Debian Lenny server and hence decided to describe my installations steps hoping this would help ppl who would like to run their own jabber server on Debian . After some research of the jabber server softwares available, I decided to install Ejabberd The reasons I choose Ejabberd is has rich documentation, good community around the project and the project in general looks like one of the best free software jabber servers available presently. Besides that ejabberd doesn't need Apache or MySQL and only depends on erlang programming language. Here is the exact steps I followed to have installed and configured a running XMPP jabber server. 1. Install Ejabberd with apt The installation of Ejabberd is standard, e.g.: debian:~# apt-get --yes install ejabberd Now as ejabberd is installed, some minor configuration is necessery before the server can be launched: 2. Edit /etc/ejabberd/ejabberd.cfg Inside I changed the default settings for: a) Uncomment%%override_acls.. Changed: %%%% Remove the Access Control Lists before new ones are added.%%%%override_acls. to %% %% Remove the Access Control Lists before new ones are added. %% override_acls. 1 / 6 Walking in Light with Christ - Faith, Computing, Diary Articles & tips and tricks on GNU/Linux, FreeBSD, Windows, mobile phone articles, religious related texts http://www.pc-freak.net/blog b) Admin User from: %% Admin user {acl, admin, {user, "", "example.com"}}.
