Use policy routing :
ip access-list extended h323-signaling
permit tcp any any eq 1720
permit tcp any eq 1720 any
deny ip any any ! Just for statistics
route-map h323-signaling permit 10
match ip address h323-signaling
set ip precedence flash
interface FastEthernet 1/0
ip route-cache policy
ip policy route-map h323-signaling
