Summary: OPTIONS problem

Initial Comment:
I have an event where two packets arrive - the first being an ACK from an reINVITE / 200 OK and the second being an OPTIONS packet.   When these are forwarded, they are actually sent in reverse order, the OPTIONS request is sent before the ACK is sent (the CSeq for the ACK is 2 and the CSeq for the OPTIONS is 3).   This is breaking the call as the CSeq is received out of order on the far-end.   I've used Wireshark to actually see the incoming order and the outgoing packets sent.   I'm using OpenSIPS v. 1.4.4 (no TLS) on a FreeBSD (64-bit) 7.1 machine.

I've even tried running SER 0.9.6 and the same thing occurs.
