Site Topology

Field	Description
Allowed via H.323-aware firewall	Allows H.323 calls to the internet through a firewall.
Allowed via H.323-aware SBC or	Enables H.323 calls to the internet through the specified session border
ALG	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	Enables SIP calls to the internet through the specified session border
ALG	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.
