Dear Team,

if CGRateS has DispatcherS enabled with the following config

I have seen the following problems :

For Requests from OpenSIPS, if sessions section has attributes conns set to *localhost then I am receiving the following error.
This was supposed to go through dispatcher engine. if section has attributes conns set to *internal system is working fine.

Responder.GetCostOnRatingPlans is not passing through DispatcherS engine.
I see that the Responder.GetMaxSessionTime method is sent correctly to the dispatcher engine but Responder.GetCostOnRatingPlans is not
