A non-transitory computer readable storage medium of a first distributed management architecture (DMA) system includes a first home location register (HLR) that stores information associated with one or more mobile subscribers that are registered with the first DMA system. The non-transitory computer readable storage medium includes a community location register (CLR) associated with a second DMA system. The CLR stores information associated with a second HLR of the second DMA system, and the second HLR stores information associated with one or more mobile subscribers that are registered with the second DMA system. The non-transitory computer readable storage medium includes instructions that, when executed by a processor, cause the processor to initiate connection of a call from a first mobile subscriber to a second mobile subscriber via the first DMA system and the second DMA system when the second mobile subscriber is registered with the second DMA system.
