Frank, yes there is a quota of 25 on the Trail Crest Exit permits, 15 available 6 months before, 10 available 2 weeks before. If you select the "exiting Mt Whitney" when looking for a trail permit, they only show available dates where BOTH your trail entry point AND the exit permit have available slots. If either quota is full, Rec.gov will show they aren't available.
Paul, yes you need to call in. I've always had pretty good luck calling in, but that's just my experience. As I wrote above they are adding the "Print your own permit" button online, so people don't need to call in now and work through email to get a permit. It can all be automatic. So they are hoping that will reduce the phone load.
The Trail Pass permit requires a phone call because there were way too many people wanting to go north on the JMT/PCT, and would select Trail Pass when Cottonwood Lakes and Cottonwood Pass quotas were full. People would indicate their camping locations, showing they were heading north, and Inyo does not allow people to do that. The are required to use the Cottonwood trails to head north. So, by phoning in, they can make sure people are actually going south or into the Golden Trout areas. Interestingly, if you call in, and are logged into Recreation.gov, while talking to them, they will open the quota for the date you want, so you can grab the permit, and then they close it. Kinda like a secret handshake.
