Misc Application (time condition) > BLF

Hi,

I wanted an extension which is only is reachable at certain times. So I deleted the existing extension 18 and added a misc application with feature code 18 and set a time condition as destination. If time matches the call is going to the new extension (181).

This works fine, but now on the other phones (SPA 509) the line keys needs to be adjusted. I would like to have all configured line key functions keep functioning without disclosing the extension behind the time condition (118).

Line key function : fnc=blf+sd+cp;sub=18@$PROXY

Any help would be appreciated.
