CHAPTER68 Configuration Parameters Reference
Mediant 1000 Gateway & E-SBC | User's Manual
Parameter Description
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.
'Prefer Routing Table'
configure voip > sip-
definition proxy-and-
registration > prefer-
routing-table
[PreferRouteTable]
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.
'Always Use Proxy'
configure voip > sip-
definition proxy-and-
registration > 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: The parameter is applicable only if a Proxy server
is used (i.e., the parameter IsProxyUsed is set to 1).
'SIP ReRouting Mode'
configure voip > sip-
definition proxy-and-
registration > sip-
rerouting-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.
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].
