There is lots of site for online video and voice call but like Skype and this is best.
I am using Skype from many year and I have so many friends on Skype and this is easy and the free way to hat talk and video chatting.
there is one more reason that this site is good because its work good in slow network too. I like this so much because its very nice in slow network. other site will create problem in low network or internet speed but this site work too good really.
join Skype and use free ceiling with your friends.
