Defines the minimum number of consecutive, successful keep-
alive messages that the device sends to an offline proxy, before the
device considers the proxy as being online. The interval between
the 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 successful 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 [SIPMaxRtx] is applied).
Note: The parameter is applicable only if the 'Proxy Keep-Alive'
parameter is set to Using Options.
Enables the proxy redundancy mode.
■ [-1] = Not configured (Default). Proxy redundancy method is
according to the settings of the global parameter
[ProxyRedundancyMode].
■ [0] Parking = If the device operates with a proxy server that
has the highest priority and the proxy then goes offline, the
device attempts to connect and operate with a different proxy
that has the highest priority of all currently online proxies.
However, once the device starts operating with this new proxy,
it remains operating with it even if a previously offline proxy that
has higher priority becomes online again.
