Your patch indeed resolves part of the issue, but it is not complete. The
problem is that set_expected_rtp in the file
net/netfilter/nf_conntrack_sip.c assumes that the source IP-address of the
expected RTP audio connection is the same as the source address of the SIP
control connection. This is not necessarily the case and prevents RTP
connections from getting through the NAT box as the expected connection
does not match the attempted connection.

As far as I can see -stable and -rc do not work in the described case. The
problem is that the sdp session that carries the audio stream is NATed
just like the SIP-control stream. This is ok when the SIP server has the
same IP as the server that handles the sdp session, but when the IPs
differ, packets that are destined for the sdp server are sent to the SIP
server instead when going through NAT.
Actually it work because that's exactly what I fixed :)
See below.
