[Users] extra accounting problem

Hi! I want to extra-account several parameters like source IP address:port, received socket, TLS parameters for the incoming connection AND the outgoing connection. The incoming connection is simple. I just copy the pseudo variables into the AVPs which are extra accountend. For accounting the outgoing parameters, I abuse the response. In the default response route I copy the socket info and TLS parameters into other AVPs (which are also marked for extra accounting). The AVPs which are filled during the request are stored in the database. But the AVPs which are filled in the response do not get filled into the DB. Is there a limitation within the ACC module? regards klaus
