Site Topology

The protocol-specific routing settings for a site determine whether and how calls from that site can traverse the firewall to reach endpoints outside the enterprise network:

●Via a transparent firewall

●Via the specified SBC

●Not at all

The site’s routing settings are used when the dial string is resolved by a dial rule using the Resolve to external address or Resolve to IP address action (rules 5 and 6, respectively, of the default dial plan; see Dial Rules on page 239).

Note: Consider Adding an SBC or SIP Peer

Alternatively, you can add an H.323 SBC (see External H.323 SBC on page 120) or a SIP peer (see External SIP Peer on page 105) that can only be reached by dialing a specific prefix or prefixes. A dial string beginning with such a prefix can be resolved by the dial rule using the Resolve to service prefix action (rule 4 of the default dial plan).

The commands in the Actions list let you add a site, edit or delete sites (other than Internet/VPN), and see information about a site, including the number of devices of each type it contains.

Note: Avoid Case-Sensitivity Issues When Entering Network Configuration

Enter all network/DNS-related information in all lower case to avoid possible case-sensitivity issues with various devices and ensure interoperability.

The following table describes the fields in the list.

Column	Description
Name	Name of the site.
Description	Description of the site.
Country Code	The country code for the site’s location.
Area Code	The city or area code for the site’s location.
Max Total Bandwidth (Mbps)	The total bandwidth limit for voice and video calls.
Max Per-Call 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.
Territory	The territory to which the site belongs, which determines the Polycom
	RealPresence DMA cluster responsible for it.
