Hi, I've noticed that in the last few years few implementations have gained popularity who use User-Agent in both requests and responses. Instead of User-Agent in requests and Server in responses which I always believed (perhaps incorrectly) to be the right way of doing it. The argument there is that "oh, our implementation is an endpont/B2BUA, not an UAS". The question hence is it my reading of RFC wrong or theirs? Thanks!
