Ringing problem on inbound calls

Here is the problem I am facing.
The call gets answered right away but there in not ring sound, it just go to IVR right away.
For Some people this maybe ok but I want to change this. Also I am experiencing problems with my first IVR audio as it gets cut off. this is also why I want to make the inbound call ring for at least one ring. Is this posible?? if it is can someone explain on a way someone that is not linux proficient can understand what to do?
thanks for your help.
