Parameter  Description 
LCR Call Length 
[RoutingRuleGroups_LCR
AverageCallLength] 
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. 
Default Cost 
[RoutingRuleGroups_LCR
DefaultCost] 
Determines whether routing rules in the Outbound IP Routing table 
without an assigned Cost Group are considered a higher cost or lower 
cost route compared to other matched routing rules that are assigned 
Cost Groups.  
  [0] Min = If the device locates other matching LCR routing rules, 
this routing rule is considered the lowest cost route and therefore, it 
is selected as the route to use (default.) 
  [1] Max = If the device locates other matching LCR routing rules, 
this routing rule is considered as the highest cost route and 
therefore, is not used or used only if the other cheaper routes are 
unavailable. 
Note: If more than one valid routing rule without a defined Cost Group 
exists, the device selects the first-matched rule.
