Version 7.2 379 Mediant 800B Gateway & E-SBC
User's Manual 17. Control Network
Parameter Description
Note:
 The parameter is applicable only to Server-type IP Groups and when
the 'Authentication Mode' parameter is set to SBC as Server (i.e.,
authentication of servers).
 To specify the SIP request types (e.g., INVITE) that must be
challenged by the device, use the 'Authentication Method List'
parameter.
Gateway
SIP Re-Routing Mode
re-routing-mode
[IPGroup_SIPReRoutingM
ode]
Defines 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).
 [-1] = Not Configured (Default)
 [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.
 [1] Proxy = Sends a new INVITE to the Proxy. This 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:
 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 redirected calls.
 The parameter is ignored if the parameter AlwaysSendToProxy is set
to 1.
Always Use Route Table
always-use-route-table
[IPGroup_AlwaysUseRout
eTable]
Defines the Request-URI host name in outgoing INVITE messages.
 [0] No (default).
 [1] Yes = The device uses the IP address (or domain name) defined
in the Tel-to-IP Routing table (see Configuring Tel-to-IP Routing
Rules on page 525) as the Request-URI host name in outgoing
INVITE messages, instead of the value configured in the 'SIP Group
Name' field.
Note: The parameter is applicable only to Server-type IP Groups.
GW Group Status
GW Group Registered IP
Address
(Read-only field) Displays the IP address of the IP Group entity
(gateway) if registered with the device; otherwise, the field is blank.
Note: The field is applicable only to Gateway-type IP Groups (i.e., the
'Type' parameter is configured to Gateway).
GW Group Registered
Status
(Read-only field) Displays whether the IP Group entity (gateway) is
registered with the device ("Registered" or "Not Registered").
