[cisco-voip] Publishing CCM through NAT disconnect call after 10 minutes

[Brain Whistler]

Hi,

I have published my call manager through static NAT on
my router with IOS 12.3.11T ipvoice. While at user end
I am using IP softphones which are running on "ip NAT
overload". 

The problem I am facing is that my every inbound and
outbound calls get disconnected after 10 minutes. 

Does anyone know where is the problem, or there is a
bug with the NAT on mentioned IOS.

Thanks
Brain
