I trying to establish a dial plane rule that let me transfer a client automatically to his/her desired destination. so for example if extension one (1001) tried to call extension four(1004) then the call should be first directed to extension zero (1000) and then automatically transfer to the destination which is (1004). I have included a diagram for what I have described . so the rule should be generic in a since that all outbound calls from clients should be transfer first to the central (1000).
your help is very appreciated
