You can assign Usage Allocation Plans (UAPs) to provide more control over a Call-by-Call Service Selection trunk group. You can allocate a minimum and a maximum number of channels for incoming and outgoing called numbers, privileged users, and voice and data calls.
With a UAP, you can set the:
Maximum number of trunks that each service can use at any given time. The sum for all services can exceed the total number of trunk group members. For example, for a 15-member trunk group, you can administer a maximum of seven MEGACOM service calls, six MEGACOM 800 service calls, and eight software-defined network (SDN) calls. Using UAP, you can ensure that a specific service does not dominate all trunk group members, yet is flexible to accommodate fluctuating demands.
Minimum number of trunks that must always be available for each service. The sum for all services cannot exceed the total number of trunk group members. For example, for a 10-member trunk group that provides access to MEGACOM service, MEGACOM 800 service, and SDN service, the minimum number of trunks to use for each of these services cannot add up to more than 10.
When these UAP limits are exceeded, the system rejects the call, even if a trunk is available. On outgoing calls, the calling party hears a reorder tone, unless other routing preferences are available.
You can assign either a fixed or a scheduled UAP for each Call-by-Call Service Selection trunk group.
With a fixed UAP, one plan applies at all times.
With a scheduled UAP, you can administer different plans to apply at different times of the day and on different days of the week. You can assign as many as six activation times and associated plans for each day of the week.
You can administer a simple fixed UAP, or a flexible UAP with many scheduling options. You can even start out with no UAP, and then build the UAP as needed.
