I picked up a Netgear WNDR3700 for $0 at some point last year, and until recently it did a great job of gathering dust. But last week I put it to work running Gargoyle v1.5.9.

However, I've hit a strange issue, phone trees no longer work, or at least the one at my kids doctor's office doesn't. I failed to find any info on the Gargoyle forums, and googling anything with the term "phone tree" included returns a whole host of un-related stuff.

Any suggestions on what the issue might be? Or should I just return this router to dust gather.
Thanks!
