h323 NAT on cisco router

[aarizvi213]

I get to know that cisco router doesnt do h323 natting properly ,, Is this correct ???

but D-link and planet routers do .

actually its looks to me the matter of IOS of cisco , so any cisco IOS available to h323 natting ???

If I used 2500 or 2600 series router with IOS release 12.1 can work , right ????

I think 1700 series routers also support ????
