Hi Nick,
Bit if a brain dump to get you started:
Firstly - I note from your attached config that your dont have RTPProxy deployed. You will find that this helps as it will act as a mid point between both ends and is visible by both so is part of solving the NAT issues with streaming media. You will need to get this deployed and update your config so that your SDP in your video invites are rewritten to make both ends us rtproxy. Start at http://www.rtpproxy.org/
Once this is done,I would start with running Wireshark in promiscuous mode on a laptop on the same wifi subnet as the iPhone and looking for the inbound INVITE and then watching for the RTP packet stream. You can now see the INVITE arriving or going out and also see if the RTP streams are there.
This might nor necessarily be just OpenSips related. - what iPhone video / voice clients are you using? You may well be running into RTP pinhole issues with the firewall / WiFi router.
When sending voice / video from the WiFi device, RTP packets are flowing out through the router and into the mobile world. When you do the reverse, the RTP stream is coming from the outside world towards your internet router and WIFi box (these might be the same or separate units). The firewall may be blocking these incoming packets. Solutions for this exist based around the receiver setting up an outgoing RTP ping to open a firewall port and then using symmetric ports in the sdp for the video. (this is more for your background understanding, getting RTP proxy set up and properly configured should help).
Hope this helps.
