This is a site I dug up with professional ringers, long in length, that when combined with VibAndRing will hold me over until we get a real solution. Works well for now, not missing calls anymore!
Save the mpi to your pc and move it onto device memory. They when you go click media, ringtones it will show. Menu >>> set to ring and you wont miss another call.
Downside, not everyone will like these tones, but they are free after all.
