Summary:                    SIP  200 OK  withou ACK
Description: 
We have the issue when happening a problem into network.

When Receive INVITE and we respond 200 OK, and this last not arrived to
the originator, then the originator resend INVITE many times. But the
*Asterisk "Answers" all this call such as if it were differents calls.

I guess this is heavy problem when will try conciliation with CDR calls.

Please can tell me if we have any mistake

Tanks

Hi Lmadsen, Now Upgrade to 1.6.2 and still the same issue.

A -> SVN-branch-1.6.2-r272459 - XXX.XXX.XXX.2XX
B -> SVN-branch-1.6.2-r281912 - YYY.YYY.YYY.3YY

Actually I run a Firewall in the mid for reproduce the issue. Since I
guess the asterisk should wait Ack before changed the disposition to
ANSWERED, and so generate inconsistency. Because a Third party bug can
cause the ack not will arrive, but the asterik I see aren´t taking this on
consideration.

May be, exist any change  to do in config within sip.conf that solvent it.
But I don´t know wich.

Best Regards,
MB.
