Hololens and Skype

hello all!
I have a question regarding connecting to Skype with my hololens... currently my hololens is not able to call or receive calls! I know that it is connected to my skype account because when i enter a new contact on my computer it does show up on the hololens. However if someone Skyped me only my computer will ring. Nothing from my hololens? And outgoing calls from my hololens just ring and ring.
Any suggestions about how to fix this?
thank you in advance!
