Steve,
As you can see in this thread, there are multiple things that can be done inside the call flow to identify who is calling or what number they are calling into, and then you can make routing decisions based on that. So, if you wanted the calls to be handled differently based on whether it is an intercompany transfer or if it is an external call, then making these changes in architect will be beneficial.
If you are just looking for numbers and reporting on these transfers vs. external calls. You can always go to Performance - Workspace - DNS Performance. Then you can filter by the numbers that point to the flow in question.
Thank you,
