Least Cost Routing (LCR)
Hytel's LCR (Least Cost Routing) is a function that can modify dialled digits before sending them to the exchange.
This feature is primarily used as a tool to re-route Long
Distance calls through the cheapest Carrier by dialling an
over-ride prefix
at a particular time of
day or day of the week, calls to specific locations, calls from specific lines or
extensions. The system does
this by removing certain digits and inserting others when
calls are made to specific numbers or prefixes.
LCR can also be used for many other purposes.
Example # 1
Calls from the Managing Director's extension could be programmed to add the Caller ID
blocking prefix "1831" before each call.
Example # 2
A certain line on the system may be provided with "Easycall Call Waiting" and a
particular person may find the call waiting tones
intrusive. That extension could be
programmed to insert the call waiting over-ride prefix to ensure that he/she is not
disturbed by
waiting calls when making outgoing calls from his/her extension.
Example # 3
A particular extension may be used for a fax machine. You may wish to ensure that all IDD
calls are routed through your Carrier's
"data-grade" IDD lines by programming
the system to remove "0011" and replace it with "0019" for Optus IDD
data-lines or "0015"
for Telstra IDD data-lines.
