Does only a single router provide access to the IP network?
In a dual network, two routers provide access to the IP network as shown in the diagram below.
However, the VoIP Gateway Card cannot take the advantage of having two routers as access
points to the IP network.
For example, if router A, whose IP address is assigned as the default gateway IP address of
the card, fails, VoIP communications are no longer possible; the card is not able to switch its
default gateway from router A to router B to access the IP network. For more details about the
default gateway setting, refer to "2.2.1 Network Parameters" of the VoIP Gateway Card
Programming Guide.
