[SR-Users] Rtpproxy re-INVITE handling

Hello,
I'm using Kamailio 3.2.4 for NAT traversal using rtpproxy_manage() in a  
largely stock script.  Everything works great until the far end (on a public  
ip) sends a t.38 re-INVITE.  The 200OK from the NATed UAC then doesn't  
trigger rtpproxy and the private IP in the sdp causes the fax to fail.  Any  
help handling these re-INVITEs would be greatly appreciated.  I'm happy to  
post traces if that helps describe the situation.  The network topology  
looks like this:

NATed UAC -> Kamailio on a public IP -> UAS on a public IP  


Thanks in advance,
Spencer
