not enforced. Only calls with media traversing the 4300T is counted towards
the bandwidth maximum.
L. 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. Please see
Configuring VoIP Survivability in EdgeMarc Appliances for more

Configure VoIP Subnet Routing
It is not necessary to configure VoIP subnet routing if all of your voice devices are
installed on the same IP subnet as the
4300T. In some installations the voice
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.
PLEASE note: VoIP Subnet Routing is separate and independent from static data
routes (see Static IP routing). VoIP subnet routes must be configured for each
LAN subnet that contains devices making use of the 4300T’s Application Layer
Gateway (ALG). These entries tell the ALG that the identified subnet is allowed to
make use of its services and what
router the ALG should use to reach that
subnet.
Enter a VoIP Subnet Route
A. Select System.
B. Select System Overview.
C. Select VoIP Subnet Routing.
D. Enter the IP Network (e.g.
10.10.12.0).
This is the IP address of the remote
subnet containing the voice devices.
E. Enter the Netmask (e.g. 255.255.255.0).
This is the mask of the IP address of the subnet containing the voice devices.
F. Enter the Gateway (e.g. 10.10.10.2).
This is the IP address of the intermediate router that knows the return path to the
remote subnet from the 4300T.
