How Can I Know on Skype if Any of My Contacts Are Talking to Someone Else?by Alex Zang ; Updated September 28, 2017
When you're on Skype, you may wonder whether one of your contacts is available to chat. Unfortunately, unless she's changed her status to indicate that she's busy or on a call, you won't be able to tell if she's available for a call without actually trying to call her. Once you have initiated your call, you'll know based on what happens to your call whether she's talking to someone else.
Log on to Skype.
Select the contact you want to call.
Click "Video Call." If you hear a busy signal or you're sent to voice mail, that means the contact is busy talking to someone else and can't take your call.
