Add Subnet Dialog Box
Lets you add subnets to the site you’re adding or editing.
Allowed via H.323-aware firewall Allows H.323 calls to the internet through a firewall.
Allowed via H.323-aware SBC or
ALG
Enables H.323 calls to the internet through the specified session border
controller (SBC) or application layer gateway (ALG).
Call signaling address (IPv4) The call signaling address for the H.323 SBC or ALG.
Port The call signaling port for the H.323 SBC or ALG.
SIP Routing
Internet calls are not allowed Disables SIP calls to the internet.
Allowed via SIP-aware firewall Enables calls to the internet through a firewall.
Allowed via SIP-aware SBC or
ALG
Enables SIP calls to the internet through the specified session border
controller (SBC) or application layer gateway (ALG).
Call signaling address (IPv4) The call signaling address for the SBC or ALG.
Port The call signaling port for the SBC or ALG.
Subnets Lists the subnets in the site. Click Add to add a subnet. Select a subnet in the
table and click Edit or Delete to modify or remove it.
Subnet Name The unique name of the subnet.
IP Address The IP address of the subnet.
Subnet Mask Length The CIDR (Classless Inter-Domain Routing) prefix size value (the number of
leading 1 bits in the routing prefix mask). This value, together with the IP
Address, defines the subnet.
For IPv4, a value of 24 is equivalent to specifying a dotted-quad subnet mask
of 255.255.255.0. A value of 16 is equivalent to specifying a subnet mask of
255.255.0.0.
Max Bandwidth (Mbps) The total bandwidth limit for voice and video calls.
Max Bit Rate (kbps) The per-call bit rate limit for voice and video calls.
Note: Bit rate is not the same as bandwidth. Since the bit rate applies in both
directions and there is overhead, the actual bandwidth consumed is about 2.5
times the bit rate selected.
