Skipe is realllly most suitable way to contact with anyone anywhere it is very useful for the official meetings to as to directly chat and make the video conferencing. Every IT company uses a skipe to contact with the clients from anywhere in the world. I am using skipe since 3 years age.
My first interview is also conducted from skpe too. Quality of the call is really good you can also use voice call service there are many options for login also you can directly login with your facebook, gmail ids.i think skipe is still best option for calling and chatting purpose, I will definitely recommend this to every friend.
