User's Manual 28. SBC Configuration
Version 6.8 497 Mediant 500 E-SBC
Parameter Description
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).
Group Policy
CLI: group-policy
[IP2IPRouting_GroupPolicy]
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).
Note: Each Forking Group can contain up to 20 members. In
other words, up to 20 routing rules can be configured for the
same Forking Group.
Cost Group
[IP2IPRouting_CostGroup]
CLI: cost-group
Assigns a Cost Group to the routing rule for determining the
cost of the call. To configure Cost Groups, see ''Configuring
Cost Groups'' on page
229 .
By default, no Cost Group is defined.
28.5.4 Configuring SIP Response Codes for Alternative Routing
Reasons
The SBC Alternative Routing Reasons table lets you configure up to 20 SIP response
codes for call release (termination) reasons. If a call (outgoing SIP dialog-initiating
methods, e.g., INVITE, OPTIONS, and SUBSCRIBE messages) is released as a result of a
configured SIP code (provided in SIP 4xx, 5xx, and 6xx), the device attempts to locate an
alternative route for the call in the IP-to-IP Routing table. Alternative routing rules are
configured with the 'Alternative Route Options' parameter set to
Alt Route Ignore Inputs
or Alt Route Consider Inputs (see ''Configuring SBC IP-to-IP Routing Rules'' on page
487 ).
