Cisco ASA port forwarding from one public > two private IP's

Hello,

Have inherited an ASA5510 and need some assistance.  Just had an NEC VOIP phone system installed and we have a single IP phone that is going to a remote site that needs UDP access through the ASA public IP > a pair of internal IP's based on port.  I'm not familiar how to do this.  Here is what I have so far:

object network nec1100_cpu
 host 192.168.0.201

obect network nec1100_cpu_out
 host <public IP>

object-group service nec1100_cpu_ports
 description Inbound ports needed for VOIP Registration
 service-object udp destination eq 5060
 service-object udp destination range 5080 5081

access-list outside_access_in extended permit object-group nec11_cpu_ports any object nec1100_cpu

object network nec1100_cpu
 nat (inside,outside) static <public IP>

object network network nec1100_cpu_out
 nat (outside,inside) static 192.168.0.201

 

Now I need to add UDP forwarding for 10020-10083 from the same <public IP> to internal IP 192.168.0.202.  How to accomplish this?

Thanks in advance!
