Is it possible to have static IP addressing?
Because the maintenance of the VoIP Gateway Card is carried out from a personal computer
(PC) through an IP network, the card must be assigned a static IP address.
Static IP addressing must be made possible even when the DHCP feature is used. For more
details, refer to "2.2.1 Network Parameters" in the VoIP Gateway Card Programming Guide.
Is network address translation (NAT/NAPT) disabled?
In a network where address translation techniques (e.g., NAT/NAPT) are used to convert
between global and local IP addresses, VoIP communications based on the H.323 protocol
cannot be carried out appropriately. Generally, NAT/NAPT are features that are available with
routers.
Note
If the router on the network supports the "H.323 NAT" feature, it may be possible to have
VoIP communications over the network. For more information, consult your network
administrator.
