[SR-Users] Dynamic CSEQ Updates

Hey kamailio team, When are the callbacks in the dialog module for updating $dlg_var(cseq_diff) called? I am trying to dynamically enable / disable cseq updates (some specific carriers need it and some don't) by setting $dlg_var(cseq_diff)=$null prior to sending the request but it seems like the callback happens after relaying. For example I tried various locations: - prior to t_relay() - in onreply_route[] - in failure_route[] - in event_route[tm:local-request] - in event_route[tm:local-response] I also tried setting modparam("dialog", "initial_cbs_inscript", 1) and calling dlg_manage() prior to routing and those didn't seem to be the right callbacks either. Either the callback that updates $dlg_var(cseq_diff) occurs after t_relay() / forward() is called or setting $dlg_var(cseq_diff)=$null has no effect. Is dynamically turning CSEQ updates on / off possible by overwriting $dlg_var(cseq_diff)? Or would this require new logic in the dialog module to be supported?
