OpenSIPS could be used to load balance media servers with the "Load Balance" module. The module provides capability to rout traffic based on the load.
The LB module defines the offered resources, and for each resource, it defines the capacity / maximum load as number of concurrent calls the destination can handle for that resource.
For an example derived form OpenSIPS docs;The destinations are assigned with their resources ready to share and as mentioned the capacities. OpenSIPS Load Balancer Module documentation on OpenSIPS Load Balancing - how it works at OpenSIPS provides detailed directions to setup load balancing a set of Yate / Asterisk servers.
