Summary:                    Responds sendrecv to recvonly SDP, but RFC 3264 says
sendonly and inactive are only possible replies
Description: 
Whilst looking at possible solutions to
https://issues.asterisk.org/view.php?id=16254, I noticed that Asterisk can
never send a sendonly SDP response.  Moreover it treats an inbound recvonly
as an unrecognized case.  The result is that it sends the default sendrecv
response.

RFC 3624 says that the only acceptable responses to recvonly are sendonly
and inactive.  I.E., reading between the lines, the response cannot offer
more capabilities than the request would allow.

---------------------------------------------------------------------- 
we have a workarround that has currently helped us to stay out of
trouble...setting "ignoresdpversion=yes" in sip.conf has suppressed the
issue...this just as a tip for others that have run into the same problem.
