    3838This callback is called when the invite session is being redirected to a new target. If there are multiple targets, then the callback will be called multiple times, once for each target. This callback will be called on these events: 
    3939 - a 3xx response containing usable Contact header(s) is received 
    40  - a 4xx or 5xx response to subsequent INVITE request is received, and the invite session has at least one more valid target to try. This happens for example when multiple Contact headers (alternate targets) are received for the original INVITE, and 4xx/5xx response is received for the second INVITE (to the first alternate target). The callback then will be called before the invite session tries to send the third INVITE to the second alternate target. 
     40 - a 4xx or 5xx response to subsequent INVITE request is received, and the invite session has at least one more valid target to try. This happens for example: 
     41    - when two Contact headers are received in the 3xx response for the original/first INVITE,  
     42    - A second INVITE is sent to the first alternate target, and 4xx/5xx response is received for this second INVITE.  
     43    - The callback then will be called before the invite session tries to send the third INVITE to the second alternate target.
