This has probably been answered a hundred times.
I have two GV numbers connected to an Obi 200. The first one, my identified dial-out, works fine when I dial to it for voicemail. The second doesn't identify the dial-out number as valid because I can't, of course, add it in GV as an additional phone line. So, it asks me to enter an associated number each time I call for voicemail.
Is there a workaround?
In the past I used this same set-up with an Obi 100 and never had this problem.
