Reroute SIP calls on no response and/or time-out

Hi,

 

Just want to know if it is a normal SBC behavior if SA is active/in-service and call initiated on this SA but received no response and this call has been time-out, should the SBC recursive and try to re-route this call to another SA in the same SAG?  My present understanding is that SA call re-routes due to failed condition (i.e., OOS), but calls' timing out?  Also, would configuration be an issue?

 

Appreciate the assistance and advise.
