I don't know about the legality of it all so can't answer that.
But as for the other....
It seems that you might be able to record a live VRS call. Quick early morning google brought me this site--
http://blogs.techsmith.com/tips-how-tos/how-to-record-skype-google-hangouts-and-webinars/
Skip down to page 10 and it tells you some info there on what you can use and how. I know it says for Skype and google Hangouts but VRS is based on the same principle as those two with video.
That's all I could find with the terms I used (I got to page 5 of my results before I gave up lol).
That sucks though about all the trouble you've been having. I recently went to a 2nd opinion eye doctor (I may be switching to him I like him and his office so much)- they were more than happy to communicate via email (I initiated through their website) and THEY were the ones who asked the best way to communicate while on the appointment before I could say anything
:jaw: Nice to see that.
