Yes and no. I had dring setup, but the problem was that I had dring on
both line 1 and line 2, and the code had no way to specify different
contexts on a per channel basis. This has not changed AFAIK. If you only
have dring on one line, and the "fax" number is a dring number (not the
primary number), then I could see it working. Otherwise, probably not.
Dring is really only useful on single ZAP FXO boxes. The SPA-3000 does
not do dring detection on the FXO port IIRC.
