User's Manual
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] Alt 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] Alt 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.
Notes:

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 561). 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 'SBC 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 whether the routing rule includes call forking.

[0] None (default) = Call uses only this route (even if
Forking Group members are configured in the rows below
it).

[1] Forking = Call uses this route and the routes of
Forking Group members, if configured (in the rows below
it).
