Version 7.2 661 Mediant 1000B Gateway & E-SBC
User's Manual 33. Routing SBC
Parameter Description
If only one Routing Policy is configured in the Routing Policies
table, the Routing Policy is automatically assigned. If multiple
Routing Policies are configured, no value is assigned.
To configure Routing Policies, see ''Configuring SBC Routing
Policy Rules'' on page 670.
Note: The parameter is mandatory.
General
Index
[IP2IPRouting_Index]
Defines an index number for the new table row.
Note: Each row must be configured with a unique index.
Name
route-name
[IP2IPRouting_RouteName]
Defines an arbitrary name to easily identify the row.
The valid value is a string of up to 20 characters. By default, no
value is defined.
Alternative Route Options
alt-route-options
[IP2IPRouting_AltRouteOptions]
Determines whether this routing rule is the main routing rule or
an alternative routing rule (to the rule defined directly above it in
the table).
 [0] Route Row = (Default) Main routing rule - the device first
attempts to route the call to this route if the incoming SIP
dialog's input characteristics matches this rule.
 [1] Alternative Route Ignore Inputs = If the call cannot be
routed to the main route (Route Row), the call is routed to
this alternative route regardless of the incoming SIP dialog's
input characteristics.
 [2] Alternative Route Consider Inputs = If the call cannot be
routed to the main route (Route Row), the call is routed to
this alternative route only if the incoming SIP dialog matches
this routing rule's input characteristics.
 [3] Group Member Ignore Inputs = This routing rule is a
member of the Forking routing rule. The incoming call is also
forked to the destination of this routing rule. The matching
input characteristics of the routing rule are ignored.
 [4] Group Member Consider Inputs = This routing rule is a
member of the Forking routing rule. The incoming call is also
forked to the destination of this routing rule only if the
incoming call matches this rule's input characteristics.
Note:
 The alternative routing entry ([1] or [2]) must be defined in
the next consecutive table entry index to the Route Row
entry (i.e., directly below it). For example, if Index 4 is
configured as a Route Row, Index 5 must be configured as
the alternative route.
 The Forking Group members must be configured in a table
row that is immediately below the main Forking routing rule,
or below an alternative routing rule for the main rule, if
configured.
 For IP-to-IP alternative routing, configure alternative routing
reasons upon receipt of 4xx, 5xx, and 6xx SIP responses
(see ''Configuring SIP Response Codes for Alternative
Routing Reasons'' on page 668
). However, if no response,
ICMP, or a SIP 408 response is received, the device
attempts to use the alternative route even if no entries are
