Kolibear - never been there, but from earlier threads on PPRuNe, ISTR that they ask for your insurance details, etc that they keep a hard copy of, hence the need for a fax. Once they have these details after your first trip, then you can phone for PPR.
I believe that I've remembered this correctly (I haven't trawled back to find the original thread, but I'm sure a search would get it for you).
