Always used to script as was ex Nortel (AACC with AML) so used to it and haven't worked on them for some time, in a script you use ROUTE CALL but in a flow I think you want to add a Finish Block, give it a name, set controlled or not depending on if you want the AACC to stay in control of the call in case it fails etc, select Route Call, add destination DN. In CS1000 would have used a Phantom or an ACD to forward to the Mobile and put that internal number in the script.
