I am a new member. I am only interested in talking and seeing my contact. Why am I asked for my contact's phone number? Isn't it posssible to just click on contact's name to reach the person?
if the contact you want to call is online, the Call button (skype-to-skype) calls will be displayed. If they are offline, the Call Phone button will be displayed instead. Try to open an online and an offline contact to see the difference.
