BMLT also has a feature-rich system for NA helplines called yap. In addition to connecting callers with NA volunteers, it can read BMLT schedule information to the caller, provide a daily meditation reading, etc. The Arizona Region is using it as part of BMLT (not sure if anyone else in the zone is or not). Existing yap installations can be re-directed to use the new zonal server once the region’s data is there, although some work will be needed to fix service body IDs and similar things.
