One of the major effects of globalization is the growing demand of cost-effective means of communication. Since the number of Internet users is constantly increasing, services based on VoIP technology have a growing demand. People often choose softphone services over regular telephony services, as using VoIP offers significant advantages in comparison with traditional phones. Replacing desk phones with softphone applications is a common tendency both in the business world and among home Internet users. The popularity of VoIP solutions is justified by the effectiveness of the softphone, as this type of application is both easy to use and has a low cost. Many people choose VoIP technology solutions, because a softphone allows them to make calls directly from their personal computers. This type of software application is very popular with Internet users worldwide because it allows not only voice data transmission, but also exchange of files of considerable sizes, including images. VoIP solutions are constantly improved and upgraded to include more and more advanced features that increase their effectiveness. Learning how to use a softphone is mainly intuitive as its interface is user friendly and similar to the mobile phones’ interfaces.

Using VoIP technology has few disadvantages, the main one being lack of mobility. Softphone users can only make calls from their PCs, which can tie them to a certain location. However, this drawback is compensated by the fact that many people use PC phones instead of regular landline phones in their workspace. High-quality VoIP transmissions also require a broadband Internet connection and are dependent on the band width available at the moment when the call is made. Heavy traffic can impede proper communication by means of a softphone. The availability of broadband Internet, however, has increased over the years leading to the fact that more and more people use PC phones. Companies which provide VoIP solutions usually offer a free software application which is easy to install and set up. The interface of any softphone has many customization options and these features help users learn how to adapt such an application to the personal needs very quickly.
