Parameter Description
'LCR Feature'
lcr-enable
[GWRoutingPolicy_
LCREnable]
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.
Note: LCR is applicable only to Tel-to-IP routing.
'Default Call Cost'
lcr-default-cost
[GWRoutingPolicy_
LCRDefaultCost]
Defines whether routing rules in the Tel-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 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 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.
'LCR Call Duration'
lcr-call-length
[GWRoutingPolicy_
LCRAverageCallLength]
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.
Alternative Routing for Tel-to-IP Calls
The device supports various alternative Tel-to-IP call routing methods, as described in this section.
IP Destinations Connectivity Feature
The device can be configured to check the integrity of the connectivity to IP destinations of Tel-to-
IP routing rules in the Tel-to-IP Routing table. The IP Connectivity feature can be used for the
Alternative Routing feature, whereby the device attempts to re-route calls from unavailable Tel-to-
IP routing destinations to available ones (see Alternative Routing Based on IP Connectivity).
The device supports the following methods for checking the connectivity of IP destinations:
■ Network Connectivity: The device checks the network connectivity of the IP destination
configured by the 'Alt Routing Tel to IP Connectivity Method' parameter:
