@henningw Hello, It is also reproducible for the younger branches (5.8 and 6.0) as the tm module has never covered this behaviour. It seems to me, user-defined wt_timer (wait_timeout) is a different issue, as it is not being propagated somewhere [from here](https://github.com/kamailio/kamailio/blob/master/src/modules/tm/timer.c#L162)
The PR above proposes a solution for the response issue. I was tested at the testbed with the expected results.
