I did run my test again, same result: works on 1.6.4, doesn't on 1.7.

The only changes in the config are the following:

1.6.4:
create_dialog();
setflag(5); # for bye_on_dialog_timeout

1.7:
create_dialog("BPp");

Here is what I noticed when looking at the output of the dlg_list command;

1.6.4
dialog::  hash=2154:1189469910
       state:: 4
       user_flags:: 0

       callee_contact:: sip:ohpwrcbd at 62.X.Y.Z:50131
       caller_cseq:: 10547
       callee_route_set::
       callee_bind_addr:: udp:91.X.Y.Z:5060

and in 1.7:
dialog::  hash=1601:1367800701
       state:: 4
       user_flags:: 0
       timestart:: 1314037262
       timeout:: 1314058862
       callid:: OrT1izagFZ07KH01VDAFZIweVVO.-d.s
       from_uri:: sip:saghul2 at sipdoc.net
       to_uri:: sip:saghul at sipdoc.net
       caller_tag:: KJB84JwXsDlfI3bFkxeX-8Y5pmzLnY83
       caller_contact:: sip:wonqjpfd at 192.168.X.Y:60942
       callee_cseq:: 0
       caller_route_set::
       caller_bind_addr:: udp:91.X.Y.Z:5060
       callee_tag:: iTa9gOmx7GtXQ3R1J96E7-dtYsrwT.Ya
       callee_contact:: sip:ohpwrcbd at 62.X.Y.Z:63447
       caller_cseq:: 322
       callee_route_set::
       callee_bind_addr:: udp:91.X.Y.Z:5060

As you can see, the caller_contact is wrong on the 1.7 output, but its ok on the 1.6.4 output.

Any clue?

Thanks and regards,
