Mediant 800B Gateway & E-SBC
Parameter Description
DNS server, using SRV records. The device sends the requests
in such a fashion that each proxy receives a percentage of the
requests according to its' assigned weight. A single FQDN should
be configured as a proxy IP address. Random Weights Load
Balancing is not used in the following scenarios:

More than one IP address has been configured for the Proxy
Set.

The proxy address is not configured as an FQDN (only IP
address).

SRV is disabled (see the DNSQueryType parameter).

The SRV response includes several records with a different
Priority value.
Min. Active Servers for Load
Balancing
min-active-serv-lb
[ProxySet_MinActiveServersL
B]
Defines the minimum number of proxies in the Proxy Set that must
be online for the device to consider the Proxy Set as online, when
proxy load balancing is used.
The valid value is 1 to 15. The default is 1.
Note: The parameter is applicable only if proxy load balancing is
enabled (see the 'Proxy Load Balancing Method' parameter, above).
Advanced
Classification Input
classification-input
[ProxySet_ClassificationInput]
Defines how the device classifies incoming IP calls to the Proxy Set.
 [0] IP Address Only = (Default) Classifies calls to the Proxy Set
according to IP address only.
 [1] IP Address, Port & Transport Type = Classifies calls to the
Proxy Set according to IP address, port, and transport type.
Note:
 The parameter is applicable only if the IP Groups table's
parameter, 'Classify by Proxy Set' is set to Enable (see
Configuring IP Groups on page 365).
 The parameter is applicable only to the SBC application.
 If more than one Proxy Set is configured with the same IP
address and associated with the same SIP Interface, the device
may classify and route the SIP dialog to an incorrect IP Group. In
such a scenario, a warning is generated in the Syslog message.
However, if some Proxy Sets are configured with the same IP
address but different ports (e.g., 10.1.1.1:5060 and
10.1.1.1:5070) and the parameter is configured to IP Address,
Port & Transport Type, classification to the correct IP Group is
achieved. Therefore, when classification is by Proxy Set, pay
attention to the configured IP addresses and this parameter.
When more than one Proxy Set is configured with the same IP
address, the device selects the matching Proxy Set in the
following order:

Selects the Proxy Set whose IP address, port, and transport
type match the source of the incoming dialog (regardless of
the settings of this parameter).

If no match is found for abo
ve, it selects the Proxy Set whose
IP address and transport type match the source of the
incoming dialog (if the parameter is configured to IP Address
Only).

If no match is found for above, it selects the Proxy Set whose
IP address match the source of the incoming dialog (if the
parameter is configured to IP Address Only.
