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
