Since version BrandMeister Core 20211222-205035 has support of DMRA AIS.
DMR Application Interface by DMR Association is a general-use IP-based interface for DMR applications and interworking. It is quite abstract and allows vendor's specific deviations. Also it is a bit slow due to complicated procedures (for example, call setup).
During the implementation we tried to provide flexibility of connector. To follow that approach most of specific procedures, such as registration business-logic are moved to Lua code of Registry. On this way, for example, you are able to register all subscribers of BrandMeister Network in an interconnected DMR Tier 3 network.
