but opensips still trying to retransmit initial invite to client...

First of all, in accordance with RFC3261 (Section 8.1.1.8) INVITE without "Contact" header must be rejected. 
I see, I can reject such message using configuration to check presentity of this header in INVITE message, but it would be better when it will be done thru the parser/tm modules by opensips.

Second is the question: why opensips try to retransmit initial INVITE when response was already recieved.
