Making a Call: Load Balancing
Calls made through an MVPGSM unit can be routed according to the Load Balancing setting. There are three types of load balancing in the MVPGSM:
First Available, LUF (Least Used First), and RR (Round Robin).
Load Balancing Options
Should you be using SIM cards that have limited service times, there are three load balancing styles that can be employed to maximize your use and
reduce extra charges. If you have unlimited service, select ‘Unlimited’ in the load balancing screen. Load balancing is tied directly to the Inbound Phone
Book. After creating a Load Balancing Group, you then need to go to the Inbound Phone Book and create the rules for the SIP end points that will take
advantage of the load balancing group.
First Available:
First available balancing will attempt to use the first channel and if that is not available, it will attempt to use the next channel in numerical order.
Least Used First:
Least Used First balancing will compare the calling plans on all channels and determine which has the highest number of minutes available per day and
use that channel (SIM).
Round Robin:
Round Robin balancing will use a self-monitored list. The first channel used will be moved to the bottom of the list after it has been used once, and the
next channel moves to the top of the list. This process rotates through all available channels set to Round Robin load balancing.
