Setting up the least-cost router
Two essential questions must be clarified with regard to configuring the least-cost
router:
쮿
Which operating modes of the
ELSA LANCOM Wireless should the services of the
least-cost router use?
쮿
Which calls should be routed over which provider?
To answer these questions, proceed as follows:
햲
In
ELSA LANconfig , go to the 'Least Cost Router' configuration section on the
'General' tab.
햳
Enable the least-cost router function. The least-cost router can only be enabled if
you have already set the unit time manually or the time has already been received
from the ISDN network itself (see also 'Time for the Selection' further below).
Activate the following operating modes for the least-cost router as required:
– Router
– LANCAPI
If you have also activated least-cost routing for the router module, connections may be
established via providers that do not transmit connect-charge information. The connect-
charge monitoring may thus be inadvertently lost. In this case, use the time budget as
an alternative.
햴
Change over to the 'Time periods and public holidays' tab. Open the
Least-cost
table
, create a new entry and enter the following data:
– Which prefix should be rerouted?
– Which provider should be used for this prefix? If you have entered several
network prefixes separated by semicolons, the LCR will automatically try the
next prefix if the current one is busy.
– On which days and what times should the routing be active? Please note that
time blocks cannot extend from one date to another (i.e. 6:00 p.m. to 6:00 a.m.).
– Should the call be handled by the default telephone provider if all call-by-call
providers are busy? If 'Automatic fallback' is disabled, the LCR will start at the
beginning after unsuccessfully trying the last network prefix.
