I'm trying to help out a new small business who has inherited a DX-120 in their new office space.

My background is in much bigger systems but I see that there's a console port to the switch.. just looks like I need the PC-DBA software.

How do I go about getting PC-DBA? I reached out to Comdial/Vertical to become a tech for them but have not gotten a response.

I can certainly program from a handset, but would rather use a software interface.
