Inyo National Forest has announced this -- If you want to talk to a live person to make a reservation, you should call the Inyo Wilderness Permit Office at 760-873-2483.

There is no change to making online reservations -- recreation.gov is still the place to go.

Here's the announcement:

The recreation.gov call center will no longer make WILDERNESS reservations...
Recreation.gov will still be responsible for campground reservations. They can also still help with resetting passwords or ID administration for a persons account.

Answers to wilderness questions and assistance with reservations for wilderness permits will be referred to the Inyo NF Wilderness office at (760) 873-2483

Recreation.gov is located in New York. I can imagine the answers people might get to questions when they call about wilderness permits for hiking in the Sierra. crazy
