LCR

Description

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.

By default 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.

Fail-over explanation

• end.

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.
