network address translation (nat) lets home office or small network environments use internal ip addresses for the devices within the network, while using one external ip address to ommunicate with the outside world (wide area network). however, many small office home office (soho) routers provide nat ervices that are not fully h.323 compliant.

    therefore, this solution is provided to enable the user make calls outside the internal network.

    at this time, it is not possible to make video conferences calls within the internal network when using the nat setting.

    to make video conferencing calls within the network when using this solution, simply de-select the system is behind a nat option and make the call. re-select the system is behind a nat option to re-activate this feature and make external calls.
