By adding some desktop VoIP software tools to your Mac, you, too, can take advantage of Internet Internet calling. We’ve reviewed four Mac-compatible desktop VoIP applications: Apple’s iChat AV 3.1.4, SIPPhone’s Gizmo Project 1.3.2, SightSpeed 4.5, and Skype 1.4.

Perhaps the best thing about these VoIP apps is that they’re free downloads and aren’t shareware, so they won’t time out or periodically nag you to register. Since these programs are free, their makers do charge for From Your Desktop Desktop Voice over IP software allows you to interact with other VoIP users, and some some premium features. VoIP tools even let you call traditional phone numbers from the comfort of your Mac desktop. To get started using VoIP, you’ll need a broadband Internet connection (cable or Cross-Platform Connections these simple desktop VoIP apps can make DSL) and a Mac running OS X 10.3 or 10.4 Some VoIP products, including Skype and conferencing easier—and more affordable.

  • Performance Analysis on Voip for Kolej Kediaman 2 & 3
    PERFORMANCE ANALYSIS ON VOIP FOR KOLEJ KEDIAMAN 2 & 3, UNIVERSITI MALAYSIA PAHANG DESMOND KO KHANG SlANG This thesis submitted in fulfilment of the requirements for the award of the degree of Bachelor of Computer Science (Computer Systems & Networking) Faculty of Computer Systems & Software Engineering UNIVERSITI MALAYSIA PAHANG DECEMBER 2014 V ABSTRACT Voice over Internet Protocol (VoIP) is a useful technology that allows users able to make unlimited free call no matter is local or international call. With this technology, the voice can be transported through over data networks. Unfortunately, the voice data will cope with some traffic that can affect the quality of VoIP calls. In this research, the maximum number of concurrent VoIP users will be estimated based on three factors which are packet jitter, packet end to end delays and MOS value. Besides, with the likes of Internet application such as video streaming, downloading of video and audio, online gaming which can directly affected the performance of VoIP. Therefore, two types of simulation scenarios can be done. First scenario is a campus network with VoIP application only. While the second scenario is a campus network with applying VoIP application and some external traffics such as HTTP and video streaming. The result these two scenarios will simulate by using OPNET modeler 14.5. In the testing phase, the number of clients in each scenario increased gradually until the threshold value for packet jitter, packet end to end delays and MOS are unacceptable. After that, the result that obtained from the simulation experiment will be analyzed and recommend the number of VoIP users for each factor.

  • THE MAINTENANCE of MUTUAL UNDERSTANDING in ONLINE SECOND LANGUAGE TALK ADAM BRANDT Thesis Submitted for the Degree of Doctor Of
    View metadata, citation and similar papers at core.ac.uk brought to you by CORE provided by OpenGrey Repository THE MAINTENANCE OF MUTUAL UNDERSTANDING IN ONLINE SECOND LANGUAGE TALK ADAM BRANDT Thesis submitted for the degree of Doctor of Philosophy Newcastle University School of Education, Communication and Language Sciences June 2011 Abstract Encounters in which at least one person is communicating in a second language (L2) are increasingly prevalent, and span many contexts and settings. However many of these settings remain under-researched, particularly those outside of formal language education (Firth & Wagner 1997, 2007; Wagner 2004). One such under-explored setting is the internet. In one particular internet context, L2 users of English have taken the opportunity to create voice-based chat rooms in which participants can practice their use of English. In such chat rooms, despite the huge variety in backgrounds and proficiencies, participants prove themselves to be highly skilled, resourceful and competent interactants, able to ensure mutual understanding as consistently and regularly as would be expected from first language users. However, as with any context involving any kind of interactants, there are occasions on which this mutual understanding appears to come under threat. This study applies conversation analysis (CA) to the examination of audio recordings of these online, voice-based chat rooms. More specifically, it provides a fine detailed examination of the work which is put in by the participants in order to pre-empt, and/or overcome, possible threats to mutual understanding (or ‘intersubjectivity’). Analysis show how participants are at times sensitive to such threats when dealing with (1) unspecified trouble in talk and (2) an absence of response to talk.
