A system and method for managing an endpoint repository of a communication platform that includes managing a set of telephone endpoints that can be in an allocated state or an unallocated state; classifying endpoints of the set of telephone endpoints with a set of classifiers; evaluating endpoint inventory across a set of endpoint classification groupings and detecting at least one classification grouping that, based in part on the allocated and unallocated state of corresponding endpoints, satisfies an inventory update condition; generating an endpoint transfer request that specifies the endpoint classifiers of the classification grouping; and selectively adding endpoints from the inventory source to the endpoint repository.
