Parameter Description
EnableProxyKeepAlive to 1 or 2.
Web: Proxy IP List
Refresh Time
EMS: IP List Refresh
Time
[ProxyIPListRefreshTim
e]
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.
Web: Enable Fallback to
Routing Table
EMS: Fallback Used
[IsFallbackUsed]
Determines whether the device falls back to the Outbound IP Routing
Table for call routing when Proxy servers are unavailable.
 [0] Disable = (Default) Fallback is not used.
 [1] Enable = The Outbound IP Routing Table is used when Proxy
servers are unavailable.
When the device falls back to the Outbound 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.
Web/EMS: Prefer Routing
Table
[PreferRouteTable]
Determines whether the device's internal 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 Outbound IP
Routing Table for a match with the Tel-to-IP call. Only if a match is
not found is a Proxy used.
Web/EMS: Always Use
Proxy
[AlwaysSendToProxy]
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: This parameter is applicable only if a Proxy server is used (i.e.,
the parameter IsProxyUsed is set to 1).
Web: SIP ReRouting
Mode
EMS: SIP Re-Routing
Mode
[SIPReroutingMode]
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.
Notes:
 When this 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].
 When this parameter is set to [2] and the INVITE fails, the device re-
routes the call according to the Standard mode [0]. If DNS resolution
fails, the device attempts to route the call to the Proxy. If routing to
the Proxy also fails, the Redirect/Transfer request is rejected.

When this parameter is set to [2], the XferPrefix parameter can be
