sending of each consecutive successful keep-alive is configured by
the 'Success Detection Interval' parameter (see below). For an
example of using this parameter, see the 'Success Detection Interval'
parameter.
The valid range is 1 to 100. The default is 1.
Note: The parameter is applicable only if the 'Proxy Keep-Alive'
parameter is set to Using Options.
Defines the interval (in seconds) between each keep-alive retries (as
configured by the 'Success Detection Retries' parameter) that the
device performs for offline proxies.
The valid range is 1 to 200. The default is 10.
For example, assume that the 'Success Detection Retries' parameter
is configured to 3 and the 'Success Detection Interval' parameter to 5
(seconds). When connectivity is lost with the proxy, the device sends
keep-alive messages to the proxy. If the device receives a
successful response from the proxy, it sends another (1st) keep-alive
after 5 seconds, and if successful, sends another (2nd) keep-alive
after 5 seconds, and if successful, sends another (3rd) keep-alive
after 5 seconds, and if successful, considers connectivity with the
proxy as being restored.
Note: The parameter is applicable only if the 'Proxy Keep-Alive'
parameter is set to Using Options.
Defines the maximum number of UDP retransmissions that the
device sends to an offline proxy, before the device considers the
proxy as being offline.
The valid range is -1 to 255. The default is -1 (i.e., the settings of the
global parameter SIPMaxRtxis applied).
Note: The parameter is applicable only if the 'Proxy Keep-Alive'
parameter is set to Using Options.
Determines whether the device switches from a redundant proxy to
the primary proxy when the primary proxy becomes available again.

[-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
