Entering a single '0' will initially reroute all numbers starting with a zero. However,
as neighboring local exchanges may also start with a '0' and yet be billed as local
calls, their prefixes should be listed separately to prevent these calls from being
rerouted. This strategy should also be applied to special prefixes such as '0800' etc.
쮿
Another strategy aims to achieve the highest possible level of control over the
routing activities. Start with the prefixes of the local area and then define the next
larger zones. The closer, and thus less expensive, tariff zones are set with longer
prefixes, the remaining more distant prefixes with a smaller number of digits.
This setting can be expanded and refined as required. Here are a number of further ideas
for your consideration:
쮿
An area code is required to dial a number of local exchanges, but these calls may be
billed as local. If these areas have been routed using a general entry, you could
route the area codes that are billed as local calls via the network prefix of your
telephone company. If the entry for the network prefix is left empty, the entry will
not be rerouted.
쮿
Perhaps a large number of your ISDN connections go to the same area codes. If
most of your remote stations are in Bristol, for example, you can reach these
numbers using a specific provider.
쮿
Study the various tariff zones. Check the Internet for the assignments of area codes
to zones at: 'http://indigo.ie/~gkernan/', for example.
Once you have found the area codes that you would like to reroute, you can start
assigning them to dial-around providers. For this, you need the current rates of as many
telephone providers as possible. These can also be found in the Internet. Addresses
such as 'http://indigo.ie/~gkernan/' in the UK, for example, contain complete, up-to-date
listings for all types of connections. With this information on hand, you can now begin
feeding your least-cost router...
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 Business 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
