Hi, I'm studing FS-2828, why freeswitch statemachine always 'remap' 180 with SDP in a 183 ? I already ported FS-2828 patch to current GIT but my patch didn't forward new SDP when 180 is received after first 183 http://pastebin.com/dqiBcYC8 My idea is to create a patch to forward all 1XX messages to calling party. Thanks Igor-
