Samsung SCH-A950

Ok I did as directed and got the 30 second music bit e-mailed to my phone.....Got them and they play fine and dandy,,,,BUT!!!! When I applied it to the phone as the ringtone, all seemed fine until a call. The ringtone starts and goes for a whole 2 seconds then silent....Then call it again and it will go fore the duration, do it again 2 seconds....Anybody got an answer for this??? They are in the qcp format(whatever that is) 😕
