Cisco are still using the wrong version. For a while when I first started looking at this (in 2008), they actually did *accept* a connection with DTLS v1.0. The handshake would work, but data packets went nowhere. There would have been an easy upgrade path for them, making the server accept *both* versions and slowly phasing out the use of DTLS1_BAD_VER on the clients. But they haven't, and in fact the server won't even do the DTLS v1.0 handshake any more these days. -- dwmw2
