Incorrect - you can enter the LD code in the forwarded number string.

Example: FWD or 355 + 8 + 15032221212 + hit the infinity/program key four(?) times + the LD code.

You may need to add more pauses, which is simple. We have lots of accounts that forward LD with codes.

If it is just one or two phones that do this you can set up phantoms to route the same way then the person just forwards to the phantom or DND/path, etc.
