In either AS or MS definitions there is a field call REVERT. That's the Access DN,where the calls go when 0 is press. But, If I'm following what you are doing, If you put in the access DN of 500 it will retrun the the same service you are in. Once you've made your changes, another access DN would need to be set up to target the original Menu.

I.E.

Access DN 500 now targets AS721.
MS500 has no Access DN since it was changed.
By setting up antoher Access DN xxx (ACDDN) with MS500 as the Menu ID
You could set the REVERT to xxx and it would go to MS500.
This can remain in the VSDN table and would not ever need to be changed.
When not used it would just hang out in the DN table.

Hope this helps.
