Hi Carsten, I tried that before but it's not what I really need. By saying that , when I added this function to my failure route then every call failure that happened (routing problem let's say) then immediately this GW was set to Inactive mode and I was not able to use it.
What I'm asking is to understand why Dispatcher module is sending calls to a GW in P state?
