Customers can use Session Manager to define the routing policy. The routing policy controls when calls are made, how the call load is balanced, and how calls are routed during network failures.
Least-cost routing, also called time-of-day routing, uses the lowest cost route from a list of service providers on a time-of-day or time-of-week basis.
Alternate routing routes calls around network failures on a global basis and uses global PSTN fallback when the internal network is unavailable.
Load balancing distributes calls. For a given SIP entity, you can administer Session Manager to select a host from multiple IP addresses based on administered priorities and weights.
Call admission control reroutes calls when the bandwidth allocation for WAN link is exceeded.
