LCR

About

LCR (Least Cost Routing) is a set of Providers that should be used to send a call when trying to dial any destination - for example, by the cheapest rate.

The correct name for such a function is a Routing Table, because the function supports other ways of routing, not just finding the cheapest route.

LCR supports fail-over. That is, if one provider fails, the next one is dialed. This is completely invisible for the caller and lets you increase the chances of the user reaching his destination. If one Provider is not capable of delivering a call, the system will try to use the remaining Providers.

To reach LCR window go to SETTINGS –> Billing –> LCR

Supported routing modes

• By Price - cheapest first (Least Cost Routing).
• By priority.
• By percent or Weight-based routing.

The user has one base LCR, so that all his calls are routed by some preset rule.

It is possible to route different destinations for a User using Call routing per destination basis.

Copying LCRs between resellers

Sometimes you need to make a LCR which takes quite a long time to make. If you have made a similar one before you can just copy it and change appropriate details. Go to SETTINGS -> Billing -> LCR -> Copy LCR (as shown below in the picture). You willl see this window:



Choose Original LCR reseller and Cloned LCR reseller and click Clone button.

Please note that LCR will not be allowed to copy if reseller B is not allowed to use Providers which are used by Reseller A.
