I think that this option would be fine, provided that we can find some
documentation that verifies that "x-nse" is in fact the same thing.  From
searching around, it looks like this has been used by Cisco stuff for quite a
while, and it just happened to always work before the recent change to not
include rfc2833 in the SDP if it was not offered to us in the initial INVITE.
