Oh, I see - this is not a bug in b2b, it is more a scripting issue.

"A" has external ip-address.
"B" is behind the NAT.
In 200 OK "B" sends its local contact, like "192.168.0.1".
So, B2B sends ACK from itself to "B" to "192.168.0.1" address instead
of external address.
It's okay because b2b knows nothing about NAT.
But with solution below I solved this problem.

Nick,
Considering the scenario A -> b2b -> B
in the so called bogus contact ( in the 200 OK reply from b2b to A) you see
the contact of B instead of the contact of b2b ?

I don't know exactly, it is bug or it is not bug.
I solved the problem this way (in global on_reply route):
onreply_route {
if ([here i filter only b2b replies]) {
if (nat_uac_test("1")) fix_nated_contact();
if ( (!search("^Content-Length:[ ]*0"))&&
(nat_uac_test("8")) ) fix_nated_sdp("10");
}
}
So, this commands executes before b2b_logic module and everything works
well.
No NAT on this host (it processed on another proxies), but nathelper
only in onreply_route used.

Hi Nick,
I noticed you closed you bug report in this - was you original report
invalid or ?

B2Blogic module changes Contact header in INVITE and other SIP
requests, but doesn't change it in 200 OK reply.
The result is ACK from UAC goes to host from untouched Contact header,
but I think that Contact should be substituted by b2blogic module to
opensips contact, then ACK will go to right destination.
