I have a Merlin Legend 7.0 with Merlin Messaging 4.0. We needed more digital telephones so we took out 2 -012 TR and installed 2 016 MLX. Realizing we were beyond the 200 port mark and could no longer assign extensions, we swapped an 008MLX for the 016MLX and renumberd the boards etc. Checked all the calling groups and coverage groups etc. The MWL will not update. The ports are set to rotary... all 12 of them. here is the card config. Slot 00 Processor 01 408 MLX, 02 408 MLX, 03 408 MLX, 04 016 MLX, 05 016 MLX,06 DS1,07 012 TR, 08 408 MLX, 09 408 MLX,10 016 MLX, 11 016 MLX, 12 016 MLX, 13 016MLX, 14 016MLX, 15 016 MLX, 16 008MLX, Mer Mes 4.0 12 port. Are we needing TTr's? or what? I checked my print out from 2010 and all looks identical with the exception of the missing TTr's. Any help is appreciated.
