Ivr configuration in free pbx

Hi everybody,

I want to make a configuration, for routing all incoming calls to a specific IVR file that i made.

A scenario for this issue can be written below,

When a person call from outside world he/she must hear “Welcome to XXX Company”

Can i do this in freepbx GUI if yes how can i do this?

If anyone knows this could you please tell me step by step?
