Parameter Description
is defined.
Alternative Route Options
alt-route-options
[IP2IPRouting_AltRouteOption
s]
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 ro
ute (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 703
). 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 configured in the
Alternative Routing Reasons table.
 Multiple alternative route entries can be configured (e.g., Index 1
is the main route - Route Row - and indices 2 through 4 are
configured as alternative routes).
Match
Source IP Group
src-ip-group-name
[IP2IPRouting_SrcIPGroupNa
me]
Defines the IP Group from where the IP call is received (i.e., the IP
Group that sent the SIP dialog). Typically, the IP Group of an
incoming SIP dialog is determined (or classified) using the
Classification table (see ''Configuring Classification Rules'' on page
677).
The default is Any (i.e., any IP Group).
Note: The selectable IP Group for the parameter depends on the
assigned Routing Policy (in the 'Routing Policy' parameter in this
table). For more information, see ''Configuring SBC Routing Policy
Rules'' on page 705.
