So CT and Oobie, I read and re-read your posts. Tell me if these are the right changes to make:
24-09 VE 252 CFNA to 3999
47-02 Delete mbox 252
47-03 Change mbox 3104 to 252, make it a Routing box, and use route box 4
47-08 Route box 4 uses DAT 4 and a 1 second timeout
47-13 DAT 4 has just one entry Timeout = Recording1 251

Will that do it?
