  1. VoIP: SIP and Skype
    SIP and Skype are the latest buzzwords in VoIP. This article explores SIP and Skype and explains how these technologies are driving the next round of the VoIP revolution. More than 30 years ago Internet didn't exist. Interactive communications were only made by telephone at PSTN line cost. Today we can see a real revolution in communication world: everybody begins to use PCs and Internet for job and free time to communicate each other, to exchange data (like images, sounds, documents) and, sometimes, to talk each other using applications like Netmeeting or Internet Phone.
     
  2. Introduction of VoIP - Better than PSTN?
    Many factors in the past have slowed the anticipated growth of Voice over IP (VoIP). Now, VoIP solutions that achieve quality and reliability, close to what we are used to from the Public Switched Telephony Network (PSTN), are emerging as the market is quickly growing. However, as will be shown in this article, there is no reason to limit the expectations to achieve only the same level of quality as in PSTN. It is quite well known that, by deploying wideband voice codecs, much better quality can be achieved. However, a little known fact is that there are ways to achieve better quality than a standard PSTN solution, even when using narrowband codecs. For example, the full available spectral bandwidth is not typically utilized in traditional PSTN solutions, something that can easily be done in a VoIP system.

  4. VoIP Tutorial - Understanding VoIP
    VoIP is fast becoming the replacement technology for voice communication. However many people still have questions as to how it works? VoIP costs less than your traditional phone service, this is what makes it attractive to most consumers. Not only does it cost less than your traditional phone service it also costs less than the vast majority of monthly cell phone plans. The number of VoIP providers is increasing giving you more choices and better calling plans. VoIP is still at its developmental stage. The VoIP service is available for both commercial and residential use, ranging from PC-to-PC service, all the way up to phone-to-phone. The following are the basic features of VoIP. Anybody with an internet connection has the basic capability to use a VoIP service and benefit from the cost savings associated with VoIP. A basic plan that offers a number of long-distance minutes is very inexpensive and if that's what you need then VoIP will work perfectly for you.
     
  5. What is Voice over IP?
    VoIP stands for Voice over Internet Protocol. As the term says VoIP tries to let go voice  through IP packets and, in definitive through Internet. VoIP can use accelerating hardware to achieve this purpose and can also be used in a PC environment. Many years ago we discovered that sending a signal to a remote destination could have be done also in a digital fashion: before sending it we have to digitalize it with an ADC (analog to digital converter), transmit it, and at the end transform it again in analog format with DAC (digital to analog converter) to use it. VoIP works like that, digitalizing voice in data packets, sending them and reconverting them in voice at destination. Digital format can be better controlled: we can compress it, route it, convert it to a new better format, and so on; also we saw that digital signal is more noise tolerant than the analog one.

  7. The VoIP overview or tutorial
    Voice over IP or VoIP technology is having a major impact on the telecommunications industry. VoIP technology provides advantages for both the user and also the provider, allowing calls to be made more cheaply, as well as enabling data and voice to be carried over the same network efficiently. In view of the way VoIP technology is being adopted, telecommunications providers are having to adopt the new technology. Already it has caused some impact on major businesses, and there will be more to come. Until recently voice traffic was carried using a circuit switched approach. Here a dedicated circuit was switched to provide a call for a user. Now with new data and Internet style technology used for VoIP, packet data and Internet Protocol (IP) is used to enable a much more efficient use of the available capacity.
      
  8. Internet DJ Console: VOIP Tutorial
    You may have noticed two small telephone icons in the bottom part of the main IDJC window. Actually I would be surprised if you haven't. Anyway, the Green Telephone allows you to stream audio from a voip service like Skype? or Teamspeak? and converse with people during your show. When in Green Phone mode your mic is open all the time and those people you are speaking with will be audible on the stream or on the recording you are making. They will not be able to hear your media players or jingles. When speaking live, the red Telephone Button allows for the people who are on the VOIP service with you to hear your show via the VOIP service at the volume level determined by the volume control which has just appeared, but not themselves take part. It is probably a good idea not to give them the full volume since they may want to speak among themselves, but on the other hand if the level is too low they won't be able to hear you announcing the next song.
