Table 14-2: Routing Rule Groups Table Description
Parameter Description
Index
[RoutingRuleGroups_Index]
Defines the table index entry.
Note: Only one index entry can be configured.
LCR Enable
[RoutingRuleGroups_LCREnab
le]
Enables the LCR feature:
 [0] Disabled (default)
 [1] Enabled
LCR Call Length
[RoutingRuleGroups_LCRAver
ageCallLength]
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 range 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, then "Weekend B" carries the lower cost.
