The bandwidth is specified in kbps and if it is set to 0, bandwidth
management is not enforced. Only calls with media traversing the 4300T
is counted towards the bandwidth maximum.
11. The Current payload bandwidth calculates the current video traffic,
without IP overhead, traversing the Appliance. The Estimated total
bandwidth calculates the total video traffic, plus IP overhead, traversing
the Appliance.
12. The H.323 Max Aliases limits the number of aliases that are allowed to
register with the Voice Appliance. If this number is exceeded when a
client tries to register, the registration will be rejected. If the value is set to
0, the maximum is not enforced.
13. The SIP LAN Side Gateway is used to configure a LAN side SIP gateway
to which calls that are not for a registered phone can be sent. The name of
the gateway is the name that is configured for the gateway in the
soft-switch and the IP address is the address where the gateway can be
reached.

Configure VoIP Subnet Routing
It is not necessary to configure VoIP subnet routing if all of your voice and
video devices are installed on the same IP subnet as the 4300T. In some
installations the voice and video devices are located in different subnets than
the 4300T and connected via intermediate routers. In these instances it is
necessary to configure a return path in the 4300T by specifying the
intermediate router who knows how to reach the voice devices. This router
must be reachable by the 4300T.
