Parameter Description
'Success Detection
Retries'
success-detect-
retries
[ProxySet_
SuccessDetectionRetri
es]
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 .
'Success Detection
Interval'
success-detect-
int
[ProxySet_
SuccessDetectionInter
val]
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 .
'Failure Detection
Retransmissions'
fail-detect-rtx
[ProxySet_
FailureDetectionRetran
smissions]
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 .
Redundancy
'Redundancy Mode'
proxy-redundancy-
mode
[ProxySet_
ProxyRedundancyMod
e]
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.
