SBCProxyRegistrationTime parameter (SBC application). Any
SIP response from the Proxy - success (200 OK) or failure (4xx
response) - is considered as if the Proxy is "alive". If the Proxy
does not respond to INVITE messages sent by the device, the
Proxy is considered as down (offline).
Notes:

Proxy keep-alive using REGISTER messages (Using
REGISTER option) is applicable only to the Parking redundancy
mode ('Redundancy Mode' parameter configured to Parking).

For Survivability mode for User-type IP Groups, you must
enable this Proxy Keep-Alive feature.

If you enable this Proxy Keep-Alive feature and the proxy uses
the TCP/TLS transport type, you can enable CRLF Keep-Alive
feature, using the UsePingPongKeepAlive parameter.

If you enable this Proxy Keep-Alive feature, the device can
operate with multiple proxy servers (addresses) for redundancy
and load balancing (see the 'Proxy Load Balancing Method'
parameter).
Defines the interval (in seconds) between Keep-Alive messages
sent by the device when the Keep-Alive mechanism is enabled.
The valid range is 5 to 2,000,000. The default is 60.
Note: This parameter is applicable only if the 'Enable 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 responses
are defined. If no responses are configured or responses received
are not those configured, the proxy is considered "alive".
Note: The SIP 200 response code is not supported by this feature.
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 valid range is 1 to 10. 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 keep-alive retries
(as configured by the 'Success Detection Retries' parameter) that
the device performs for offline proxies.
The valid range is 1 to 30. The default is 10.
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 SIPMaxRtxis applied).
Note: The parameter is applicable only if the 'Proxy Keep-Alive'
parameter is set to Using Options.
