Here is an old note that I apparently typed up:

Setting up Auto attendant on the SBX:

In order to have touch tones work when calls are directly ringing
to the auto-attendant you have to go in to CO LINE LIST and choose
the lines and click refresh and the right click choose UPDATE TOOL
Check Mark the DISA on/off box and then put the VMIB message in the
Box next to it

Once again I'm going back sometime and haven't really worked on the SBX in a long time.
