This is a question of your own business rules.

The most common way to do it is to use something like the 'permissions'
module. Build a 'trusted' table with all your Asterisk gateway IPs, and
then do the following when you receive an initial INVITE:

   if(allow_trusted()) {
      # Must be from platform gateways to customer - treat as
      # "inbound".

      ...
   } else {
      # Do authentication challenge and treat as "outbound"
      # from customer softphone.

      ...
   }
