There is a false notion regarding the term high speed VoIP that is, they are the transference of data at a faster pace. In reality this concept proves to be wrong. In simple words it suggests merely the transference of data through high bandwidth lines. Here transmission of voice data is delayed or brought to a halt by line congestion.
When VoIP was introduced initially, line congestion used to happen. That is when the PCs faced really hard time coping with the slow net connections through dial up systems. The process of converting the voice data in to data digital packets took a good amount of time as it was done over the phone lines. Insufficiency of bandwidth was the main drawback faced by these phone lines. This resulted in wastage of time before reaching the internet gateway. This situation was no better at the receiving end were the PC was connected to a low bandwidth phone line.
Downloading a single page took more time and required more patience. All you did was to wait and wait when you were connected to the net. The unit needed time to convert packets in to voice signals, and that waiting would have been worth if the sound quality was good enough. However, this was reversed with poor sound quality and voice lagged in between the conversation. The talk which could have been entertaining and fun would end up with frustration.
The situation is totally changed due to the improvements made in technology. Most homes and offices can enjoy enhanced internet experience with the provision of high speed DSL or cable lines connection. Here the voice data is zipped through the connection pipe. At the other end the receiver is satisfied with the call as he is not adversely affected in any way. He finds it no different from that of a conventional telephone call. Time and high quality is favoured through this system.
Although the high speed VoIP is irrelevant when calls are made to and from Internet phones. Here the transference of data is much similar to that of email that was send through the internet. This movement is made possible as a result of the operation of broadband line that is connected to the Internet. Further the data is divided into small units in packets from a respective server to the corresponding IP address. It is here where the term packet switching technology for VoIP becomes apt. At the destination point the reconverting of signals takes place. This is facilitated with the help of an adaptor which is connected to an internet phone.
To conclude high speed data essentially means the size of the bandwidth rather than the high speed or low speed.
