22-04 is set for the three extensions. Those three extensions answer calls to the main number. VM is inmail.
Looks like I need to set DIL no answer to something, like 16.

If I set up a routing VM box to answer in mode 2, how should messages be sent to 100 without a separate VM box? Callers could dial 0, but it would still ring before going to VM.

Thanks for the suggestions.
