User's Manual 372 Document #: LTRT-27055
Mediant 1000B Gateway & E-SBC
Parameter Description
[ProxySet_ProxyKeepAliveTime
]
sent by the device when the Proxy Keep-Alive feature is enabled
(see the 'Proxy Keep-Alive' parameter in this table).
The valid range is 5 to 2,000,000. The default is 60.
Note: The parameter is applicable only if the 'Proxy Keep-Alive'
parameter is set to Using Options.
Keep-Alive Failure Responses
keepalive-fail-resp
[ProxySet_KeepAliveFailureRes
p]
Defines SIP response codes that if any is received in response to a
keep-alive message using SIP OPTIONS, the device considers the
proxy as down.
Up to three response codes can be configured, where each code is
separated by a comma (e.g., 407,404). By default, no response
code is defined. If no response code is configured, or if response
codes received are not those configured, the proxy is considered
"alive".
Note: The SIP 200 response code is not supported for this feature.
Success Detection Retries
success-detect-retries
[ProxySet_SuccessDetectionRe
tries]
Defines the minimum number of consecutive, successful keep-
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_SuccessDetectionInt
erval]
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.
Failure Detection
Retransmissions
fail-detect-rtx
[ProxySet_FailureDetectionRetr
ansmissions]
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.
Redundancy
Redundancy Mode
proxy-redundancy-mode
Determines whether the device switches from a redundant proxy to
the primary proxy when the primary proxy becomes available
