Hi Kamailio users
How can I get a failure route to trigger in timeout-to-CANCEL in
a parallel forking scenario?
Parallel forking test scenario
1. one(the main - 0) branch picks up the call
2. 2nd branch sends CANCEL (expecting 487 etc) - but the callee does not
send any replies
No failure route handlers are called on timeout of this CANCEL - that is
kamailio attempts the CANCEL 4 times but neither
tm.t_on_failure_route, tm.t_on_branch_failure handlers are called.
Any suggestions on how to resolve this?
