Hello;
    there are 2 kamailio sip communacting each other but there is a problem second kamailio truncate sdp messages. i posted a "rtpproxy truncate sdp" 1 day ago, but i think it is kamailio that truncate it. i closed rtpproxy and some uac functions to solve problem but didnt work. i couldnt find even debug mode? 2 day past  to solve this problem . is there any experinece about it?

Thanks
