I'm seeing this on On Call's web site:

They keep taking our annual premiums, too! We found them through Insure My Trip, but they didn't come up when I used their trip planner just now.

We have UN medical insurance, which is good around the world, so we needed medical evacuation that covered longer stays. At least up until now, On Call membership has been good for trips up to 60 days. We come back to the States for a couple weeks, which we like to do anyway.
