Hello, indeed, there was a change in the behaviour based on the links you provided. It was not safe to use $T_req() in other route blocks. Maybe for event_route[dialog:start] would still be ok, because it is executed only on 200ok for INVITE, but dialog:end can be executed on dialog timeout, without any request/reply within dialog being processed at time.
The solution is to store the source IP of the request avp/xavp (I think this event route is executed after corresponding transaction match), or in a dialog variable or in htable (using callid/from tag as a key).
