Load Balancing
There are three types of Load Balancing available for calls originating from the IP network and going out to
the cellular network: First Available Hunting (often just referred to as ‘Hunting’), Least Used First
(abbreviated as LUF), and Round Robin (abbreviated as RR).
First Available Hunting:
First Available Hunting will search through the available channels and use the first SIM that presents itself as
available for use.
Least Used First:
Least Used first will compare the calling plans for each channel and select the one that has the most
remaining minutes available. This is determined by dividing the Minutes remaining / Days remaining and the
channel with the largest result remaining will be used first.
Round Robin:
With Round Robin load balancing, the channels are treated as a list and once a channel is used, it goes to the
bottom of the list and the next channel comes to the top of the list and is ready for use.
