Hi again.

Note that RFC 3261 assumes parallel forking in a different way as OpenSer 
does. OpenSer just replies **one** final response to UAC but notes what RFC 
3261 says:

------------------------------------------------------------------------
13.2.2.4 2xx Responses

   Multiple 2xx responses may arrive at the UAC for a single INVITE
   request due to a forking proxy.  Each response is distinguished by
   the tag parameter in the To header field, and each represents a
   distinct dialog, with a distinct dialog identifier.
------------------------------------------------------------------------


Of course, I can't understand how a UAC could handle various 200-OK when 
establishing a dialog, RFC dreams I hope...
