Finally I find a root of a problem with my T.38 reinvites.
A->(NAT)->Kami->PSTN
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?
