SIP routing on SBC

Hello Experts,

 

I am reading about SIP routing feature on SBC, I have a SD 4500 runing SC(x) 6.2.0 and I want to use local route table feature.

 

I have two session agents and the call will be  routed depending on the destination number on R-URI I configured one local policy:

                                       *
        to-address
                                       *
