Number Translation of Trunks for outgoing calls not working

Target: add prefix 1234 for DNIS for all outgoing calls
Example: destination number is 87654321, sending outgoing call to supplier becomes 123487654321
Action: Tried to put /1234 or "/1234" in number translation of trunks settings

But not working, outgoing call still sending out 87654321 without prefix

attached FS debug log for reference
