I can also confirm this happening with Google Voice, i'm sure that this kind of behavior is common with services like Google Voice (Where you can ring multiple endpoints) something doens't get cleaned up in the middle and it just keeps going.

I've also seen this behavior when the called number isn't actually a mobile - but is something like google voice with
multiple ring destinations one of which is the users mobile phone. In that case, nothing causing it on FreeSwitch side -
it's just flakiness with GV.
