Hello,
About fix_nated_contact () problem has been resolved.
Thanks for your help.
The reason is that when k2 sent to k1 200 ok, k1 should not do
fix_nated_contact to ua1.
k2 received ack signal must be ua2 uri address
k2 debug:
DEBUG: <core> [parser/msg_parser.c:624]: SIP Request:
DEBUG: <core> [parser/msg_parser.c:626]: method: <ACK>
DEBUG: <core> [parser/msg_parser.c:628]: uri:
<sip:5001005 at 122.116.37.55:59453;transport=TCP;ob>
DEBUG: <core> [parser/msg_parser.c:630]: version: <SIP/2.0>
