Parameter Description
Web: Redundancy Mode
EMS: Proxy Redundancy Mode
[ProxyRedundancyMode]
Determines whether the device switches back to the primary
Proxy after using a redundant Proxy.
[0] Parking = device continues working with a redundant
(now active) Proxy until the next failure, after which it works
with the next redundant Proxy (default).
[1] Homing = device always tries to work with the primary
Proxy server (i.e., switches back to the primary Proxy
whenever it's available).
Note: To use ProxyRedundancyMode, enable Keep-alive with
Proxy option (EnableProxyKeepAlive = 1 or 2).
Web: Proxy IP List Refresh Time
EMS: IP List Refresh Time
[ProxyIPListRefreshTime]
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 'Tel to IP
Routing' tablefor call routing when Proxy servers are
unavailable.
[0] Disable = Fallback is not used (default).
[1] Enable = 'Tel to IP Routing' table is used when Proxy
servers are unavailable.
When the device falls back to its 'Tel to IP Routing' table , the
device 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 if the device's internal routing table takes
precedence over a Proxy for routing calls.
[0] No = Only a Proxy server is used to route calls (default).
[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.
Web/EMS: Always Use Proxy
[AlwaysSendToProxy]
Determines whether the device sends SIP messages and
responses through a Proxy server.
[0] Disable = Use standard SIP routing rules (default).
[1] Enable = All SIP messages and responses are sent to a
Proxy server.
Note: Applicable only if 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 = 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 (default).
[1] Proxy = Sends a new INVITE to the Proxy. Note:
Applicable only if a Proxy server is used and the parameter
