
[-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.
Note:

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 the Proxy Hot-Swap feature, whereby the device switches
to a redundant proxy upon a failure in the primary proxy (no
response is received).

[0] Disable = (Default) Disables the Proxy Hot-Swap feature. If a
failure occurs in te primary proxy, the device does not connect
with any other address (proxy) configured for the Proxy Set.

[1] Enable = The device sends SIP INVITE/REGISTER
messages to the first address listed in the Proxy Address table
that is configured for the Proxy Set. If a SIP response is
received and this response code is configured in the Alternative
Routing Reasons table (see Configuring SIP Response Codes
for Alternative Routing Reasons on page 530) for SBC, or in the
Reasons for Tel-to-IP Alternative Routing table (see Alternative
Routing Based on SIP Responses on page 713) for Gateway,
the device assumes that the proxy is down and sends the
message to the next available proxy (address) in the list.
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
