Proxy Keep-Alive
Time
proxy-keep-alive-time
[ProxySet_ProxyKeep
AliveTime]
Defines the interval (in seconds) between keep-alive messages 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_KeepAlive
FailureResp]
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_SuccessD
etectionRetries]
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_SuccessD
etectionInterval]
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_FailureDet
ectionRetransmission
s]
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 .
