RE: [reSIProcate] INVITE and re-INVITE without SDP, how can I share the improves ?


FYI - you should only really be concerned with the following 3 .dot files - the 
rest are older versions:
dum-serverinvite-state.dot
dum-invite-connected-state.dot
dum-clientinvite-state.dot

Note:  The changes for accepting a re-INVITE without an SDP were incorporated 
into these files recently.
