Note: The default SBC Routing Policy is assigned the default LDAP
Server Group ("DefaultCTRLServersGroup").
Enables the Least Cost Routing (LCR) feature for the Routing Policy.

[0] Disable (default)

[1] Enable
For more information on LCR, see ''Least Cost Routing'' on page 273.
Defines whether routing rules in the IP-to-IP Routing table that are not
assigned a Cost Group are considered a higher cost or lower cost route
compared to other matched routing rules that are assigned Cost Groups.

[0] Lowest Cost = (Default) The device considers a matched routing
rule (belonging to the Routing Policy) that is not assigned a Cost
Group as the lowest cost route. Therefore, it uses the routing rule.

[1] Highest Cost = The device considers a matched routing rule
(belonging to the Routing Policy) that is not assigned a Cost Group as
the highest cost route. Therefore, it is only used if the other matched
routing rules that are assigned Cost Groups are unavailable.
Note: If multiple matched routing rules without an assigned Cost Group
exist, the device selects the first matched rule in the table.
Defines the average call duration (in minutes) and is used to calculate the
variable portion of the call cost. This is useful, for example, when the
average call duration spans over multiple time bands. The LCR is
calculated as follows: cost = call connect cost + (minute cost * average
call duration).
The valid value is 0-65533. The default is 1.
For example, assume the following Cost Groups:

"Weekend A": call connection cost is 1 and charge per minute is 6.
Therefore, a call of 1 minute cost 7 units.

"Weekend B": call connection cost is 6 and charge per minute is 1.
Therefore, a call of 1 minute cost 7 units.
Therefore, for calls under one minute, "Weekend A" carries the lower
cost. However, if the average call duration is more than one minute,
"Weekend B" carries the lower cost.
