User's Manual

[-1] Not configured = (Default) Proxy redundancy method is according
to the settings of the global parameter, ProxyRedundancyMode.

[0] Parking = The device continues operating with the redundant (now
active) proxy even if the primary proxy returns to service. If the
redundant proxy subsequently becomes unavailable, the device
operates with the next configured redundant proxy.

[1] Homing = The device always attempts to operate with the primary
proxy. The device switches back to the primary proxy whenever it
becomes available.
Notes:

To enable this functionality, you must also enable the Proxy Keep-Alive
feature (see the 'Proxy Keep-Alive' parameter in this table).

The Homing option can only be used if the 'Proxy Keep-Alive'
parameter is set to Using Options.
Enables load balancing between proxy servers of the Proxy Set.

[0] Disable = (Default) Disables proxy load balancing.

[1] Round Robin = A list of all possible proxy IP addresses is compiled.
This list includes all IP addresses of the Proxy Set after DNS
resolutions (including NAPTR and SRV, if configured). After this list is
compiled, the Proxy Keep-Alive feature (enabled by the 'Proxy Keep-
Alive' and 'Proxy Keep-Alive Time' parameters in this table) tags each
entry as "offline" or "online". Load balancing is only performed on proxy
servers that are tagged as "online". All outgoing messages are equally
distributed across the list of IP addresses. REGISTER messages are
also distributed unless a RegistrarIP is configured. The IP address list is
refreshed every user-defined interval (see the ProxyIPListRefreshTime
parameter). If a change in the order of the IP address entries in the list
occurs, all load statistics are erased and balancing starts over again.

[2] Random Weights = The outgoing requests are not distributed
equally among the Proxies. The weights are received from the 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.
