User's Manual 24. Routing
Parameter Description
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.
24.4 Alternative Routing for Tel-to-IP Calls
The device supports various alternative Tel-to-IP call routing methods, as described in this
section.
24.4.1 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' on page 542).
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:
