Lets say 99.3.81.66 is your public IP and ISP is on INT G0/0
ip nat inside source list 1 interface GigabitEthernet0/0 overload
ip nat inside source static tcp 10.3.81.6 443 993.81.66 443 extendable
ip nat inside source static tcp 10.3.81.61 80 99.3.81.66 80 extendable
access-list 1 permit 10.3.81.0 0.0.0.255
Int G0/0
ip nat outside
int g0/2
ip nat inside

Contact your network engineer they will do the needful..
also provide him (list H323 port for VC )for opening at firewall end.

you can use the nat in tcp/udp port ej:
serv1:80
serv2:21
publicip:80 ---> serv1:80
publicip:21 ---> serv2:21

NAT have three types:
static NAT: when you assign one public IP to one private IP.
Dynamic NAT: when you have a pool of public IPs that is mapped to a pool of private IPs.
overload NAT: when you have single public IP and a pool of private IPs, and it will use private IP user ports or process ID to built NAT table...
Use Nat overload method
