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

@Leif i understand what you mean, and asterisk acts as it should by
retransmit the 200 ok until T1*64 is reached and then drop the call but it
should handle the incoming invites (which are retransmits) not as a new
call.

i have looked at the code and the Ignoring this Invite message doesnt
cause anything to the dialog of this message.

@marhbere you could try to set "pedantic=yes" in the sip config. With this
enabled asterisk use a stricter method to find the old dialog and so this
may not happens.
