Summary:                    200 OK retransmitted even when first SIP OK is ACKed
Description: 
I looked at sip callflow in asterisk and seems, that asterisk retransmits
SIP/OK, even in case that first SIP/OK was correctly ACKed by other party.
If you look at attached call graph analysis, you can see it,
also, asterisk delayed initial INVITE about 200ms, before it forwards to
another party, why?

I must also notice, that my asterik server was 100% idle, only one call
was processed, when this dump was taken. Call was over LAN connection.
