MBID is reported when the MAX/TNT does NOT receive the caller-number, so I
question if BellSouth can disable Caller-ID....also you could do a PRI
trace on the MAX of the incoming call to verify the contents - i.e. see if the
caller-ID info element is included.

[debug - "pridisp 256" should do it, "pridisp off" to turn off tracing].
