I have one R13.10.1.E Total Access 912 (2nd Gen) - decided that use last firmware is best idea
Simple sip register trunk

Look at the sip trace that was made with "debug sip stack messages" - txt in attach
Inside 23:29:05.544 SIP.STACK MSG SIP/2.0 183 Session Progress I received Contact: <sip:firstname.lastname@example.org:5060;transport=udp>But all packets have to come from SBC ip only.
I decide to make simultaneous log of this call from SBC side and what I seeContact: <sip:email@example.com:5060;transport=udp>
Of course with this bug Adtran send all responses to 126.96.36.199 and 188.8.131.52 never get those and drop the call.
Progress and first OK in attachment as pictures from sngrep
What firmware is more stable for this gateway?
