Note: The parameter is applicable only if the 'Proxy Keep-Alive'
parameter is set to Using Options.
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.
■ The parameter is applicable only if the 'Proxy Keep-Alive'
parameter is set to Using OPTIONS.
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.
