VOIP has been in existence for many years but its implementation in the past have faced many difficulties and problems. There are 2 main reasons for this:

Data packets originated from Asia would typically traverse through the US before arriving in another location in Asia. Today, many Asian ISPs have peering arrangements with each other and this has helped the internet performance to improve tremendously creating the environment for successful VOIP implementation.
