I think I found how to set the push to work in the background. The problem is there are 2 places to set up Notifications. First:
Go to "Settings" and scroll down to the "Skype" settings. Make sure "Sign In Automatically" is ON and "Go Offline" is set to Never. Then below the "Notifications" sould be set with "Sound" and Alerts" ON.
Then go to "Settings>Notifications>Skype". Make sure "Notification Center" is ON, "Alert Style" is set to Alerts and "Badge App Icon", "Sounds" and "View in Lock Screen" are ON.
That should do. If you can't find the Notification>Skype try turning the Skype Setting OFF then ON. That should make it appear.

Ideas? iOS ans skype versions are identical.
i tried the fix suggested by shyfoxx and activated skype in the notifications center... I know see a badge on the screen when there is an incoming call, but still no audible ring tone. Sux.
I had same problem, no incoming ring but could hear conversation. I discovered that mute was switched on. It appears that it only affected the incoming ring sound and not the voice. My mute was hidden because I have the side switch set to lock rotation. Use 4 finger swipe up to reveal open icon bar then sideways swipe along lower screen icons to reveal the mute icon and check it has no strike through it.
Hope this helps solve your problem.
