[Users] Module tm, function t_lookup_request

[Bogdan-Andrei Iancu]

actually
    if ( !is_method("ACK|CANCEL"  && t_check_trans())
       exit;

will be better - note that t_check_trans() returns 1 for CANCEL if there 
is a corresponding INVITE transaction case when you want to process the 
CANCEL and not to discard it :).
