Details:

Dear fans,

I am trying to written a SIP demo applications by using exosip2 in windows OS,
and I also used wireshark to capture sip details. 

It looks like exosip2 in windows always send 2 straight requests within 0.1 ms
(see sip trace file 1), NOTE: I can make sure I only call exosip sending
function once. I can also make sure that 2 strangt requests are not for
re-transmition, cause re-transmition interval is normally 500ms. 
 
I tried the same codes in Linux and compile it successfully in GCC, but what
made me strange is it's OK, i.e., only 1 request sending out (see sip trace
file 2).

So I am suspecting if there were some potential bugs in exosip, used in
windows platform. 

Thanks in advance.
