CHAPTER72 Configuration Parameters Reference
Mediant 800 Gateway & E-SBC | User's Manual
Parameter Description
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].
■ When the 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 the parameter is set to [2], the XferPrefix
parameter can be used to define different routing
rules for redirect calls.
■ The parameter is disregarded if the parameter
AlwaysSendToProxy is set to 1.
'DNS Query Type'
configure voip > sip-
definition proxy-and-
registration > dns-query
[DNSQueryType]
Enables the use of DNS Naming Authority Pointer
(NAPTR) and Service Record (SRV) queries to resolve
Proxy and Registrar servers and to resolve all domain
names that appear in the SIP Contact and Record-
Route headers.
■ [0] A-Record = (Default) No NAPTR or SRV
queries are performed.
