Along with the development of the era and technology, the global world that makes the boundaries between countries increasingly disguised to be closer to the community. Now certainly not a stranger anymore if we have friends or acquaintances of people from different countries, or even from a different continent though, because of the ease of internet technology available. That way, the communication process that occurs is not only limited to the people closest but also includes global or international calls.
Thus, the rapid development of rates for international calls has led to an alternative method of communicating. One method that is currently developing is the Voice Over Internet Protocol (VoIP) that offers the benefits of cheap international calls. VoIP or Internet Telephony (Internet Telephony) is a technology capable of passing voice, video and data traffic in the form of packets over an IP (Internet Protocol) network.
Growth and technological development in every country in the world continues to grow rapidly from day to day. Given this technology has provided many benefits and influences that have a major impact on the social life of the community. This technology can facilitate the public in obtaining information, sending data, doing office work and school work, and the current trend is to establish relationships with others through social media.
Every society in the world can easily interact with each other to communicate. If the ancient days of communicating were difficult because of the time and distance it would have to write a letter that arrived for weeks or months, and even to meet distant relatives or friends we had to travel long distances that took a long time. Yet another case with today, we can communicate easily. To communicate we can use social media whose type is very diverse, ranging from Facebook, Twitter, Instagram, BBM, Line and others.
