Years ago, making an international conference call was a pricey venture and also lacked in quality, making it difficult to conduct business across oceans and around the world. Back in the mid-1900’s when audio conferencing was first introduced across international lines, a live operator was required. Today, with all the changes in technology that have taken place, international phone conferencing has changed for the better. All users need to do is dial a specified phone number and enter their access code to be immediately connected to others around the world. In addition, an operator is no longer needed.
