How to Make Cheap VoIP calls

Have you ever needed to make an intercontinental call, but you felt that it would be a waste of money because its quality is not worth the cost? Then here is what you need: in order to make high-quality and low-cost calls you only need to start making use of the opportunities that VoIP calling provides you.

Voice over Internet Protocol (VoIP)directs the way how voice signals and multimedia sessions are transmitted via the Internet. It does so by digitalising voice signals first, then it packs them into data packets, which are ordered according to codecs for faster transmission. Then, as soon as they reached their destination, they are put back in order and converted back into voice signals heard in the spakers or headphones.

This is the technology that VoIP calling uses. When you dial a number from your VoIP application (like Skype), your call will be transmitted to any desired telephone via the Internet, as shown in Figure 1.

If you wish to call a PSTN number, however, then the process is slightly different. (PSTN stands for Public Switched Telephone Network, which includes the landline and mobile telephone lines installed in the 20^th century.) Then those data packets need to be converted back into analog data before they reach the PSTN.

This is part of the service that most providers of free PC (Personal Computer) to PC Calling providers charge to a small amount. These service providers usually offer PC to PC calls for free, but it is not mobile enough, neither is it always comfortable, since your customers are not always around their PC, so it's worth investing that small amount into PC to Phone calls.
