[SR-Users] Reinvite, rewrite reply SDP?

Finally I find a root of a problem with my T.38 reinvites.


When NATted caller does reinvite, and remote side answers with 200 
OK+SDP,  Kami (why?) doesn't rewrite SDP for its own IP (so NATted 
caller can receive RTP) and leaves remote's IP as media address, so of 
course there is no RTP/UDPTL. All other NAT related stuff works fine. 
Even if remote side sends me T.38 reinvite first, everything works 
properly. Config file is default from Kami sources.

Any ideas?
