Very strange problem that I only have on the iPad. When I receive a call on Skype the ring tone keeps ringing even after I have answered the call. In fact it keeps going after I hang up the call. Sometimes it continues to ring a few times EVEN after I quit the app all together. I am to a point that I have to answer a call, tell the person I'll call them back, hang up, quit, wait, restart the app, and then place an outgoing call to the person.
