In a matter of minutes you could be set-up and making calls with your free Voip service. Voip is the future for telecommunication, its taking the internet and business communities by storm.
Getting connect to free Voip It is simple to download any of these free VoIP enabled Instant Messengers. You simply go to their websites, and click on installation/download links for the applications and follow the instructions. You will need speakers and a microphone-and of course, a soundboard. If you would like to incorporate video with your Instant Messaging, you can hook up a small digital camera or web cam.
In order for your voice to transmit digitally through the internet, you need to be sure you have enough bandwidth to facilitate the communication link. A minimum of a DSL line is required, but most larger companies will want a T1 line – a dedicated link directly to the internet that is guaranteed to be up over 99.999% of the time. Once you have your high-speed internet connection taken care of, it’s time to select a VoIP Service Provider – the company that will actually route your digitized voice signal to a real telephone on the other end. In essence, your VoIP Carrier will become your long distance carrier.
Other benefit of VoIP lies in the prioritization of the digitized voice signals that are generated when you speak. In the event no one is talking, the VoIP line does not transmit any data. This allows your T1 line to dynamically allocate bandwidth as it is needed, instead of permanently blocking out an entire channel of data.
However, the packets are not sent in a sequence. They are even routed across different paths to avoid congestion. This may not matter for e-mail, but it makes a big difference for real-time audio and video applications. For a conversation to be possible, the data packets have to arrive in the right order, and on time. That is why the first voice services were not of a good quality.
Security is an important issue and VoIP systems have to deal with Network Address Translation systems (NATs) and firewalls. Some VoIP systems can do NAT and firewall traversal, though others need to use SBCs (Session Border Controllers) for this.
The major one using 911 with VoIP because the call is made from your data network and not a conventional land line. 911 will not be able to trace the phone call made from your free VoIP phone and obtain your address. Also, the operator will not receive any of your location information.
