User's Manual
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
516). 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).
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 491).
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 518.
Defines the SIP dialog request type (SIP Method) of the incoming SIP
dialog.
