Version 7.2
Note: To use this Proxy Redundancy mechanism, you need to
enable the keep-alive with Proxy option, by setting the parameter
EnableProxyKeepAlive to 1 or 2.
Defines the time interval (in seconds) between each Proxy IP list
refresh.
The range is 5 to 2,000,000. The default interval is 60.
Determines whether the device falls back to the Tel-to-IP Routing
table for call routing when Proxy servers are unavailable.

[0] Disable = (Default) Fallback is not used.

[1] Enable = The Tel-to-IP Routing table is used when Proxy
servers are unavailable.
When the device falls back to the Tel-to-IP Routing table, it
continues scanning for a Proxy. When the device locates an
active Proxy, it switches from internal routing back to Proxy
routing.
Note: To enable the redundant Proxies mechanism, set the
parameter EnableProxyKeepAlive to 1 or 2.
Determines whether the device's routing table takes precedence
over a Proxy for routing calls.

[0] No = (Default) Only a Proxy server is used to route calls.

[1] Yes = The device checks the routing rules in the Tel-to-IP
Routing table for a match with the Tel-to-IP call. Only if a
match is not found is a Proxy used.
Determines whether the device sends SIP messages and
responses through a Proxy server.

[0] Disable = (Default) Use standard SIP routing rules.

[1] Enable = All SIP messages and responses are sent to the
Proxy server.
Note: The parameter is applicable only if a Proxy server is used
(i.e., the parameter IsProxyUsed is set to 1).
Determines the routing mode after a call redirection (i.e., a 3xx
SIP response is received) or transfer (i.e., a SIP REFER request
is received).

[0] Standard = (Default) INVITE messages that are generated
as a result of Transfer or Redirect are sent directly to the URI,
according to the Refer-To header in the REFER message, or
Contact header in the 3xx response.

[1] Proxy = Sends a new INVITE to the Proxy.
Note: This option is applicable only if a Proxy server is used
and the parameter AlwaysSendtoProxy is set to 0.

[2] Routing Table = Uses the Routing table to locate the
destination and then sends a new INVITE to this destination.
Note:

The parameter is applicable only to the Gateway application.

When the parameter is set to [1] and the INVITE sent to the
Proxy fails, the device re-routes the call according to the
Standard mode [0].
