Probably not, check the dialplan. See why 100 is being sent out the trunk, you probably just want to set your outbound route that is pretty greedy called Neb Sip.d to order 901.
I'm guessing that's the issue as immediately before this REGEX pass is Regex (PASS) [default_caller_id] which is position 80 in the default dialplan. Leads me to believe the outbound route has the default of 100.
As for why it doesn't do it with other numbers is: ${user_exists}(false) =~ /false/. I can't remember what constitutes a user in FreeSwitch, other than extensions obviously.
