SIP User's Manual
Determines whether Keep-Alive with the Proxy is enabled or
disabled. This parameter is configured per Proxy Set.

[0] Disable = Disable (default).

[1] Using OPTIONS = Enables Keep-Alive with Proxy using
OPTIONS.

[2] Using REGISTER = Enable Keep-Alive with Proxy using
REGISTER.
If set to 'Using OPTIONS', the SIP OPTIONS message is sent
every user-defined interval, as configured by the parameter
ProxyKeepAliveTime. If set to 'Using REGISTER', the SIP
REGISTER message is sent every user-defined interval, as
configured by the parameter RegistrationTime. Any response from
the Proxy, either success (200 OK) or failure (4xx response) is
considered as if the Proxy is communicating correctly.
Notes:

For Survivability mode for USER-type IP Groups, this
parameter must be enabled (1 or 2).

This parameter must be set to 'Using OPTIONS' when Proxy
redundancy is used.

When this parameter is set to 'Using REGISTER', the homing
redundancy mode is disabled.

When the active proxy doesn't respond to INVITE messages
sent by the device, the proxy is tagged as 'offline'. The behavior
is similar to a Keep-Alive (OPTIONS or REGISTER) failure.
Defines the Proxy keep-alive time interval (in seconds) between
Keep-Alive messages. This parameter is configured per Proxy Set.
The valid range is 5 to 2,000,000. The default value is 60.
Note: This parameter is applicable only if the parameter
EnableProxyKeepAlive is set to 1 (OPTIONS). When the
parameter EnableProxyKeepAlive is set to 2 (REGISTER), the
time interval between Keep-Alive messages is determined by the
parameter RegistrationTime.
Enables the Proxy Hot-Swap redundancy mode per Proxy Set.

[0] No = Disabled (default).

[1] Yes = Proxy Hot-Swap mode is enabled.
If Proxy Hot-Swap is enabled, the SIP INVITE/REGISTER
message is initially sent to the first Proxy/Registrar server. If there
is no response from the first Proxy/Registrar server after a specific
number of retransmissions (configured by the parameter
HotSwapRtx), the INVITE/REGISTER message is resent to the
next redundant Proxy/Registrar server.
