Ya I had used Skype its really a good setup for making intenational or overseas calls without any payment.I find it very comfortable for online chatting and this is the most used business software for chatting purpose.
Skype is incredible. I use it everyday for business and plesure. No video calls for me but everyone can use the chat. International contact is easy and instant. Consider it one of the best platforms that you can use for instant communication.
I heard about that but i think skype is a good tool of communication between family and friends and also good for business communication. I never used it but thinking to use skype for business conversation!
