Site Topology
Polycom, Inc. 280
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).
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.
The following table describes the fields in the list.

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).
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.
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.
