Least Cost Routing (LCR):
Allows setting the system to check the numbers dialed by extensions to find the
most economical route for establishing the calls.
When an extension activates
Automatic Line Access
by dialing “
9
”, instead of the
CO dial tone, he receives the internal dial tone. Then, the system compares the
digits he dials with the pre-programmed prefix table and as soon as it finds a match,
it calculates the most economical route based on the pre-programmed parameters.
After such a match is found, a line is selected (it may be a specific line related with
the prefix or any idle line) and a prefix of at most 6 digits (if present) is added in
front of the digits extension dials and this number is sent to the CO If no match is
found, any idle line is accessed and the number is sent to the CO, after the 6
th
dialed digit. (The same working principle applies to Selective Line Access on
system software 3.10B or better.)
IMPORTANT
It is not recommended to use this program unless necessary (if more than one
