With the advancement of technology over the past decade, communication has become much easier globally. Online tools like Skype have enabled users to call their loved ones over the internet in order to avoid the charges that are accrued with traditional long distance.
VOIP is a method where phone signals are transmitted through the web instead of regular phone lines. Calling someone in another country can be expensive without VOIP due to the cost of connecting the calls. This can be very costly if the call is being made to a remote location that requires multiple connections.
Using refurbished VOIP phone systems is a wise investment if international calling is done often. The overhead in connecting calls is eliminated, so the bill becomes fractional to what it would be with regular long distance. The sound quality is also clearer since they travel over high-speed connections versus older analog lines. This advancement enhances the experience of talking to people in other countries and should become commonplace once everyone is aware that this is the way of the future.
