Linphone a Good Working Skype Voice Over IP Alternative 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 Linphone a good working Skype voice over IP alternative Author : admin If you never tried linphone I warmly recommend it. 2 days ago, with a friend of mine we tested a bunch of Linux softwares to find out what is the situation with possible alternatives to Skype to transmit Voice and Video. I've been interested into Skype Alternative programs since about 2 years, but so far I never found good and easy to set up working Linux alternative. We first tried Ekiga. Though it is said to be a good Linux SKype alternative, my ekiga client running on Debian Linux stable Squeeze ver. 3.2.7.2 failed to connect to SIP account I've created on ekiga.net. I've tried hard to make ekiga connect to account SIP created from ekiga.net but all time I was getting an error on connect: Ekiga did not manage to configure your network settings automatically. You can still use it, but you need to configure your network settings manually. Please see http://wiki.ekiga.org/index.php/Enable_port_forwarding_manually for instructions After continously trying to follow instructions from above pointed URL and making proper settings on my DL-524 Wireless Router and all time ending up with the annoying error, we decided to finally completely abondoned it and try some other voice over IP clients. We tried Jitsi and few others which prooved to be unworking. Finally we give a try to Linphone which seemed to be promising. We tested it On Linux platform, where both of Linux installed OS-es where tested were running Debian Linux (one stable Debian Squeeze and one unstable Debian Blackstar). Linphone even with different versions on different Debian Linux OS-es worked fine Video conferences were crashing but voice over IP via SIP protocol works okay. Setting up linphone to do speak (voice over IP) conference calls with friends is easy task, you need to have linphone package installed, i.e. run: apt-get install --yes linphone 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 Then once installed launch it from terminal or GNOME menus with: $ linphone-3 You will have to create account on linphone.org's website via Register a Linphone account. Once registered and confirmed the account, linphone sends you an email with credential info, through e-mail like: Dear Linphone user, your account has been activated. You can now use your linphone account with these parameters : Sip identity : sip:[email protected] Username : hipo Domain / Proxy : sip.linphone.org Regards, The Linphone team. Then in linphone you should configure new created Linphone account via: Linphone -> Preferences -> Manager SIP Account 2 / 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 Once account is added, calls via SIP protocol are ready to go. Probabl,y due to incompitability between versions of Debian stable Linux and unstable the user you will add and about to call is showing as offline, however calling between each other works perfect and voice quality is quite good. 3 / 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 Linphone has a version for Windows as well as for AppleIphone mobile phone. For console geeks, there is also a command line tool interface to linphone linbphonec; $ linphonec Warning: Could not start UDP transport on port 5060, maybe this port is already used. Ready Warning: video is disabled in linphonec, use -V or -C or -D to enable. linphonec> linphonec> help Commands are: --------------------------- help Print commands help call Call a SIP uri chat Chat with a SIP uri terminate Terminate the current call answer Answer a call autoanswer Show/set auto-answer mode 4 / 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 proxy Manage proxies soundcard Manage soundcards webcam Manage webcams staticpic Manage static pictures when nowebcam ipv6 Use IPV6 refer Refer the current call to the specified destination. nat Set nat address stun Set stun server address firewall Set firewall policy call-logs Calls history friend Manage friends play play from a wav file record record to a wav file quit Exit linphonec register Register in one line to a proxy unregister Unregister from default proxy duration Print duration in seconds of the last call. status Print various status information ports Network ports configuration speak Speak a sentence using espeak TTS engine codec Audio codec configuration vcodec Video codec configuration ec Echo cancellation mute Mute microphone and suspend voice transmission. unmute Unmute microphone and resume voice transmission. nortp-on-a Set the rtp_no_xmit_on_audio_mute configuration parameter --------------------------- Type 'help ' for more details. linphonec> quit 5 / 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 Another great thing about Linphone is it is licensed under free software license GPL2 - meaning source is publicly accessible - thus anyone with skills and desire to port it to any computer architecture can do it. I did not have time to test it throughfully with newer version of linphone to know if Video calls works fine - whether same program versions are used between both peer sides, nevertheless for anyone willing non M$ sniffed channel to do voice calls between Computers linphone is nice. 6 / 6 Powered by TCPDF (www.tcpdf.org).

The motivation for H the research arises from problems detected in the remote 1 4 2 interaction with embedded devices over dynamic wireless networks in such systems. The selected approach is based on the application of the small- world paradigm to cyber-physical systems. It is here assumed that the concept of small world, "six degrees of separation", can be expanded to also cover communication with wireless embedded devices in cyber-physical systems context. The main contributions are the technical enablers referred to as dynamic communication spaces, dynamic M2M service spaces, configuration and remote use of services, communication overlay, access systems selection, integrated mobility, secure ad hoc networking, situated opportunistic communication, hierarchical networking for small-world networks, and short-cuts for network optimization. The enablers have been evaluated as separate technical methods and means by means of experiments and/or simulations. According to the evaluations, the enablers seem to work well as separate building blocks and that they can be combined to expand the concept of small world to also cover communication with embedded devices. Wireless short-cuts can improve the scalability and efficiency of dynamic wireless networking and weak links are essential in the neighbour discovery process.

  • Policy Options and Regulatory Mechanisms for Managing Radicalization on the Internet
    Policy options and regulatory mechanisms for managing radicalization on the Internet Paris, 30 September 2016 “[…] I firmly believe that in a free democratic society, freedom of speech and expression is one of the most prized freedoms which must be defended and upheld at any cost and this should be particularly so in the land of Voltaire. It is indeed unfortunate that in the world of today, when science and technology have advanced the frontiers of knowledge and mankind is beginning to realize that human happiness can be realized only through inter-dependence and cooperation, the threshold of tolerance should be going down. It is high time man should realize his spiritual dimension and replace bitterness and hatred by love and compassion, tolerance and forgiveness.” Justice Prafullachandra Bhagwati Dan Shefet (Individual Specialist) ACKNOWLEDGEMENTS The author wishes to thank the following for their support, valuable advice and input throughout the drafting of the Report: Dr. Indrajit Banerjee and his team in UNESCO’s Knowledge Societies Division The UNESCO Delegates and Ministries of Justice/Interior of countries that have participated in the Country Survey.

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.
